Question

A store offers a 15% discount on all items in the store during a sale. All store employees get an additional 10% employee discount. In the equation below,
C represents the cost of an item for an employee including tax and x represents the original price of the item:

C = 0.765x + 0.06(0.765x)

Chris is an employee at the store. He plans to buy a coat during the sale. The price of the coat before the discount is $100. How much will Chris pay for the coat during the sale?

Answer 1

x = 100

Plug in your equation, C.

C = 0.765(100) + 0.06[0.765(100)]
C = 76.5 + 0.06(76.5)
C = 76.5 + 4.59
C = 81.09

After the discount, Chris will pay $81.09 for the coat.
