Answer: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.
