You have become the master of making peach cobbler. The recipe you follow is simple: 22 ounces of peaches in heavy syrup 1 regular yellow cake mix 3/8 cup melted butter The biggest problem is making sure you have enough ingredients. The above recipe for one batch serves 9. The cobbler is always made in the same batch size. There are no partial batches. Having some left over is ok, but being short is not. It's also ok to have some peaches and some butter left over. Create a program that will ask the user to enter the number of servings desired. Then generate the shopping list for all ingredients. Also calculate the leftover ingredients and the leftover cobbler Peaches come in cans of 29 ounces and 15 ounces Butter comes in packages of 1 pound (2 cups). Use a separate method to calculate and return the number of cans of peaches to buy. Use a separate method to calculate and return the boxes of butter. Output should look similar to the following. Spacing may vary, but make things line up! Fill in the numbers for the hashtags. USE VARIABLES.
