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?

idk

ivettef365 · Answer

or just plug in the formula you have

C = 0.765x + 0.06(0.765x)    where x = 100 (price of coat)
C = 0.765(100) + 0.06(0.765(100))
C = 76.50 + 0.06(76.50) 
C = 76.50 + .46
C = 76.96

wait I did something wrong

C = 76.50 + 0.06(76.50)
C = 76.50 + 4.59
C = 81.09
