Question

Someone help me?

Answer 1

what do you need help with?

Answer 2

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 3

I'm pretty sure you just have to substitute 100 for x... :)

Answer 4

C = 0.765(100) + 0.06((0.765(100))
C = 76.5 + 0.06(76.5)
C = 76.5 + 4.59
C = 81.09

Answer 5

You can check that is right because the sale is 15% off and the coat is $100.
100 - 15% = 85
And employees get an extra 10% off.
85 - 10% = 76.5
And a 6% sales tax.
76.5 + 6% = 81.09
