Question

NEED HELP!

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

We need to plug in $100 for x and solve for C, the cost. Plugging in we get:
\[C=(.765)(100)+.06(.765)(100)\]
\[C=76.5+.06(76.5)\]
\[C=76.5+4.59=81.09\]
