A company sells to cleaning products
Bluemagic (for bathroom) sells for $5.00 per bottle and costs $1.50 to produce
Kitchen magic(for kitchen) sells $6.00 per bottle and $2.00 to produce

Customers charged 2.00 per order for shipping and handling. But it costs the company only $0.50 to ship each bottle.

If a customer orders more than 5 bottles on an order they get: 10% off their total product cost and free shipping and handling.

Sample run:
enter order number (-1 when done) 90210
enter product (B(athMagic) or (K(itchenMagic)> K
enter number of bottles > 2
Order 90210 2 bottles KitchenMagic
Price of order:$12.00 + $2.00 shipping
Please pay: $14.00

// this continues until the user enters a -1 for order number
// after this happens the following totals are printed
Bottles sold
120 bottles BathMagic (60.0%)
80 bottles KitchenMagic (40.0%)

Total revenue collected $xx,xxx.xx
Total cost of producing and shipping $xx,xxx.xx
Total profit $xx,xxx.xx
Average profit per order $xx,xxx.xx

Notes: Total Revenue collected: Sum of all customer payments
Total cost of producing and shipping: Total cost to manufacture and ship all items sold
Total profit= total revenue-(cost to produce and ship)
Average profit per order= total profit/ number of orders
