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.

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?

$81.09?

$$C=.765\times 100+.06(.765\times 100)$$
$$C=76.5+.06\times 76.5$$ then a calculator would work, or you can be fancy and rewrite this as 
$$C=(1.06)\times 76.5$$ but i would still use a calculator
