Answer:
16.6/ cd
Explanation:
if the tax was .90 for each CD, you times that by 3 bc there are 3.
.90*3= 2.7
If the total was 52.50, then subtract 2.7 to get the price for the 3 cds without tax.
52.50-2.7= $49.8
Divide 49.8 by 3 because there are 3 cds and you get 16.6, which is the price for one cd before tax
