Lemonade Stand Program

Assume you run a lemonade stand. Instead of messing around with a specific price, you just kind of make them up as you go, depending on how much you like the customer. At the end of the day, you want to figure out the average price you charged per cup.

Write a program that allows the user to enter 3 items:

1. The number of cups at the beginning of the day
2. The number of cups at the end of the day
3. Total sales for the day

The program should calculate and report the:

1. Total number of cups sold

2. Average price per cup
