You arrive in front of a bridge that you must cross to reach a village before dark. Crossing the bridge is not free - the bridgekeeper asks you to roll two dice to determine the cost. You decide to write a program to verify that he is charging the right price.
Your program should read two integers, between 1 and 6, representing the values of each die. If the sum is greater than or equal to 10, then you must pay a special fee (36 coins). Otherwise, you pay twice the sum of the values of the two dice. Your program must then display the text "Special tax" or "Regular tax" followed by the amount you have to pay on the next line.
When Jacob Steinberg began his trip from California to Vermont, he filled his car’s tank with gas and reset its trip meter to 0. After traveling 324 miles, Jacob stopped at a gas station to refuel; the gas tank required 17 gallons. Jacob wants a program that calculates and displays his car’s gas mileage at any time during the trip. The gas mileage is the number of miles his car can be driven per gallon of gas. Desk-check your solution’s algorithm using 324 as the number of miles driven and 17 as the number of gallons used; then desk-check it using 280 and 15.
An instructor gives a series of exams during the semester in her math class. At the end of
the semester she drops each student's lowest test score before averaging the scores. She has
asked you to design a program that will read a student's test scores as input and calculate
the average with the lowest score dropped. Here is the algorithm that you developed:
Get the student's test scores.
Calculate the total of the scores.
Find the lowest score.
Subtract the lowest score from the total. This gives the adjusted total.
Divide the adjusted total by 1 less than the number of test scores. This is the adjusted average.
Display the average.
The test scores are in a text file named scores.txt and contains the following:
Mickey, 71.0, 42.0, 83.0
Donald, 94.0, 73.0, 72.0, 81.0
Minnie, 95.0, 85.0, 45.0, 55.0, 65.0
A sample run is as follows:
Enter a file containing floating point numbers: scores.txt
Test scores for Mickey: ['71.0', '42.0', '83.0']
Removed the lowest score of 42.0 for Mickey

- A county collects property takes on the assessment value of property, which is 60 percent of the property's actual value. For example, if an acre of land is valued at #10,000, it assessment value is $6,000. The property tax is then 72 cents for each $100 of the assessment value. The tax for the acre assessed at $6,000 will be $43.20. Write a program that asks for the actual value of a piece of property and displays the assessment value and property tax.arrow_forwardSuppose you deposit the same amount of money in a bank account each month at a given yearly interest rate and you want to know the value of the account at the end of each month. Write a program that prompts the user to enter a monthly amount you deposit in the account (could contain cents) and a yearly interest (e.g., 4.25). The program will first print the values you entered for monthly deposit and yearly interest rate, followed by the six, monthly calculations showing the month number and value of the account at the end of each month (with two decimal places) up to and including the 6th month. Sample output for $200 monthly deposit and 10% interest rate: monthly deposit: 200.0 yearly interest rate: 10.0 month 1 value: 201.66 month 2 value: 405.0 month 3 value: 610.04 month 4 value: 816.79 month 5 value: 1025.26 month 6 value: 1235.47 Let's get started.

- Display the first N magic numbers, where N is a positive number that the user provides as input. Here, a magic number is a number whose sum of its digits eventually leads to 1. For example, 1234 is a magic number because 1 + 2 + 3 + 4 = 10 and 1 + 0 = 1, while 1235 is not (1 + 2 + 3 + 5 = 11 and 1 + 1 = 2). Write a program that prints out the first N magic numbers, seven on each line. You are required to use the following function prototype: bool isMagic(int value); // Returns true if value is a magic number The outline of this function will be as follows: Step 1: Calculate the sum of digits of the value Step 2: Repeat Step 1 until we get a single-digit Step 3: If the resulting sum is equal to 1 then it is a magic number, otherwise not Here is the sample output:arrow_forwardYou have been asked to write a program to play rock-paper-scissors. Your program will ask the user to input a number 0, 1, or 2 to denote rock, paper, and scissors respectively. Your program will then randomly generate a number 0, 1, or 2 to denote the computer’s hand. The rules for the game are: •A scissor can cut paper. •A rock can knock a scissor. •A piece of paper can wrap a rock. Let the game run continuously until either the user or the computer wins 3 times, displaying the outcome of each hand. At the end of the game, display a message indicating whether the user or the computer wins Helpful Hint: import random player2= random.randint(0, 2)arrow_forwardAirline companies apply baggage restrictions for their passengers. An airline company has decided to apply a 10kg limitation for passengers' hand luggage and 20kg for their normal baggage. When passengers arrive, they enter their hand and normal luggage weight from the keyboard. If passengers exceed their normal baggage allowance of 10 dollars per gram, they pay 12 dollars per kg. Accordingly, write the program that calculates the baggage price of the airline they will go to according to the baggage values entered by the arriving passenger and keeps this from closing the program for each passenger. Note: If hand and normal baggage allowances are stretched below the maximum value, the payment amount will be considered not negative. An example printout is given on the right.

- A county collects property taxes on the assessment value of property, which is 60 percent of the property’s actual value. If an acre of land is valued at $10,000, its assessment value is $6,000. The property tax is then 75¢ for each $100 of the assessment value. The tax for the acre assessed at $6,000 will be $45. Write a program that asks for the actual value of a piece of property and displays the assessment value and property tax.arrow_forwardWrite a program that calculates how much money you’ll end up with if you invest an amount of money at a fixed interest rate, compounded yearly. Have the user furnish the initial amount, the number of years, and the yearly interest rate in percent. Some interaction with the program might look like this: Enter initial amount: 3000 Enter number of years: 10 Enter interest rate (percent per year): 5.5 At the end of 10 years, you will have 5124.43 dollars.arrow_forwardWrite a program that calculates how much money you’ll end up with if you invest an amount of money at a fixed interest rate, compounded yearly.

- Need this written in the PYTHON language. Step 1: Ask the user to enter the length of their room (in feet). Step 2: Ask the user to enter the width of their room (in feet). Step 3: Calculate the area (in square feet) of the room by multiplying the length and the width of the room. For example, if a room is 20 feet wide by 24 feet long, then its area is 20 * 24 = 480 square feet Step 4: Display a menu that asks the user how much shade the room gets. The menu should have the following options: Little Shade Moderate Shade Abundant Shade Step 5: Determine the capacity of the air conditioning unit that is needed for a moderately shaded room by using the information in the table below. Room Size (sq. ft) AC capacity (BTUs/hr) Less than 250 5,500 250 to 500 10,000 501 to 1,000 17,500 Over 1,000 24,000 If the room has little shade, then the BTU capacity should be increased by 15% since the air conditioning unit must be able to produce extra…arrow_forwardSometimes we write similar letters to different people. For example, you might write to your parents to tell them about your classes and your friends and to ask for money; you might write to a friend about your love life, your classes, and your hobbies; and you might write to your brother about your hobbies and your friends and to ask for money. Write a program that prints similar letters such as these to three people of your choice. Each letter should have at least one paragraph in common with each of the other letters. Your main program should have three method calls, one for each of the people to whom you are writing. Try to isolate repeated tasks into methods.arrow_forwardf. A laborant in a laboratory does a number of antigen tests in one day. Write a program that simulates the number of antigen tests done in a day in a laboratory, displays the number of positives and negatives, and calculates the % of positives in one day. Your program needs to first generate a random number that will show the number of tests done in a day. One laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one). Then for each of the tests, your program needs to generate a random number to show whether they are positive or negative. In order to write this program, you need to have the following three functions used by the main function: test result (void): This function generates a test result. It should randomly return either one or zero. 1 means positive test result and 0 means negative test result. float positive percentage (int,int) : This function takes the total number of positives and the total number of tests and returns the % of positives.…arrow_forward
