4. Selling Cookies

The program takes 2 user inputs:

• start → the amount of money we had before selling cookies

• String of b or c

  • num_cookies → a string of character ‘c’s to denote the number of cookies sold

    • Example: cccccc → 6 cookies!

  • num_big → a string of character ‘b’s to denote the number of big cookies sold

    • Example: bbb → 3 big cookies!

The program should output:

1. Number of total cookies sold

2. Profit (which is calculated as profit = sales - cost of cookie)

   1. Cost of Normal Cookie per cookie → $1.25

   2. Cost of Big cookie per cookie → $2.00

   3. To make a normal cookie → $0.50

   4. To make a big cookie → $0.75

3. Total amount of money after selling cookies
