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.

    all you need to do is let x = 100 and calculate 0.765x + 0.06(0.765x)

    (0.765*x) + (0.06*(0.765)*x) = 76.5 + 0.06*(0.765)*x = ?

    that isn't the correct answer, please try one more time we can split the problem into two parts: 1. 0.765*x 2. 0.06*(0.765)*x you found the first part, which is 76.5 now find the second part: 0.06*(0.765)*x = ?
