Question

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.

Answer 1

Answer 8

i got 76.5

Answer 9

right, keep going with the rest of the equation

Answer 10

i add 76.5 to 0.06

Answer 11

nope, remember order of operations. multiply first, then add

Answer 12

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

Answer 13

76.56

Answer 14

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 = ?

Answer 15

0.0459

Answer 16

not quite, try one more time... remember that x = 100

0.06*(0.765)*x = ?

Answer 17

4.59

Answer 18

right, now we add parts 1 and 2 together

76.5 + 4.59 = ?

Answer 19

81.09

Answer 20

yup, that's our final answer
