Allan Arnold · Answer 1

Find the amount the store marked up the CDs by.

12.95 *.08 = 1.034 which rounds to 1.04

Add that to the former price.

12.95 + 1.04 = 13.99

Multiply by 4 to see how many 4 CDs cost.

13.99 * 4 = 55.96

Multiply by. 1 to see how much the discount is.

55.96 *.1 = 5.596 which rounds to 5.60

Subtract the discount from the original price.

55.96 - 5.6 = 50.36

It costs $50.36 to buy four CDs this year.
