Flowchart Practice
You work at a color copy center. Your boss would
  like a new windows application for the sales
  staff. The basic requirements are as follows:
• User’s should be able to input the number of copies and
  the paper type.
• Copies usually cost $1.00 each. If the customers
  purchase 50 or more copies, they get a discounted price
  of $0.80 each.
• The total price is calculated by multiplying copies x
  price.
• The program should display the number of copies, paper
  type, and total price.
• Please draw a flowchart and a storyboard for the
  following application.                                16
