The average cost of a college textbook is $125. There is a premium of 20% on hardcover text and a discount of 5% on sales of more than 4 textbooks. Write a program to prompt the user for the appropriate inputs and compute and display the before-tax cost of the textbooks.Sample calculation:price of 10 hardcover text = 10 * 125 + premium –discountprice = 1250 + 20% of 1250 – 5% of 1250price = $1437.50price of 8 softcover text = 8 * 125 –discountprice = 1000 – 5% of 1000price = $950price of 2 softcover text = 2 * 125price = $250
Question 1
Write a program that asks the user to enter the number of passengers in an airplane and the
weight of baggage for these passengers. Your program should then print the average weight
of all baggage; it should also print the weights in reverse order.
Sample run:
Enter the number of passengers in the airplane: 8
Enter the weights of 8 baggage: 16 45 60 13 24 29 50 30
The average weight of all baggage is 33.375
The entered weights in reverse order are 30 50 29 24 13 60 45 16
Write a program that calculates the total grade for N classroom exercises as a percentage. The user
should input the value for N followed by each of the N scores and totals. Calculate the overall
percentage (sum of the total points earned divided by the total points possible) and output it as a
percentage. Sample input and output is shown below.

- Write a program that reads from the user the registration fees, number of credits required for a student to finish the course, the credit price, and the number of years the student is planning to finish the whole track. The program should calculate the cost to be paid by the user each year. Payment = (credit price X number of credits) / years + registration fees The below Sample Run is to calculate the yearly payment of a course having 60 credits, 250$ for credit, 100$ for registrations fees each year, and 3 years to finish the track: using java Sample Run: Please enter registration fees, credit price, number of credits, and number of years: 100 250 60 3 The yearly required payment is: $5100.0arrow_forwardThe Café Noir Coffee Shop wants some market research on its customers. When a customer places an order, a clerk asks for the customer’s zip code and age. The clerk enters that data as well as the number of items the customer orders. The program operates continuously until the clerk enters a 0 for zip code at the end of the day. When the clerk enters an invalid zip code (more than 5 digits) or an invalid age (defined as less than 10 or more than 110), the program reprompts the clerk continuously. When the clerk enters fewer than 1 or more than 12 items, the program reprompts the clerk two more times. If the clerk enters a high value on the third attempt, the program accepts the high value, but if the clerk enters a negative value onthe third attempt, an error message is displayed and the order is not counted. At the end of the program, display a count of the number of items ordered by customers from the same zip code as the coffee shop (54984), and a count from other zip codes.
