Previous Weeks scenario

Scenario:
Your algorithm will keep track of a customer’s purchases at the local fireworks stand. Customers will
not know exactly how many items they will purchase, so using a FOR loop on this lab is not allowed.
Let’s keep the rules simple.
1) Accept the dollar value of each item purchased from the user until the useris finished.
2) When purchases are complete, enter a sentinel value of -1. (Make certain you do not
include the -1 sentinel value in your total).
3) Keep track of the total dollar amount of all fireworks purchased.
4) Keep a tally of the number of items purchased.
5) If more than 20 items were purchased, give your customer a 10% discount on their total
purchases.
6) Once purchases are complete, display the total number of items purchased, the average
price of the items, the total of all fireworks purchased, any discount if applicable & the
total of all fireworks purchasedminus the discount.

finished) : “ = Purchase(Count)

IF Count>20
Total = Sum * .90
