Question

Please show your work when you answer. So, Lightning Lucy's burnable cd's are on sale this month for 10% off regular prices. If a pack of 10 blacks cds normally cost $15, how much do you pay per CD?

Answer 1

You would find the price of the sale on the pack, 15 - 15 x .1 = 15 - 1.5 = 13.5

then divide that by 10 to get $13.5 / 10 = $1.35 per CD
