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.

replace x by 100 and compute
a calculator would help

anonymous · Answer

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

anonymous · Answer

that would be 0.765(100)+0.06(0.765(100))
so 81.09
pretty sure
