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?

First step is you break it down. The coat costs 100 bucks.
Apply the 15% discount to that coat. 100 * .15 is 15 dollars. So we subtract that from 100 to get 85. 
Next take that 85 and apply his employee 10%. 10% of 85 is 8.5 so 85-8.5 is 76.5.
the coat will cost him 76.5 dollars.

I'm not sure what that formula for C is, was that given to you?

Then my only other guess is to plug in 100 into x in your equation.
