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? Remember, do not include the $ symbol. (1 point)

Answer 1

The function for the purchase by an employee is given by
C = 0.765x + 0.06(0.765x); where x is the original price of the item.
Here, x = $100

Therefore, the amount he pays is:
0.765(100) + 0.06(0.765(100)) = 76.5 + 0.06(76.5) = 76.5 + 4.59 = 81.09

Therefore, Chris will pay $81.09 for the coat.
