A hand-held digital music player was marked down by 1/4 of the original price. a. If the sales price is $128.00, what is the original price? b. If the item was marked up by 1/2 before it was placed on the sales floor, what was that the store paid for the digital player.?

A) you would divide $128 by 4, getting $32. then add that to the original price, being $160.
B) you would divide $160 by 2, getting $80, then add those two together in order to find what it was marked up to, being $240. hopefully this helps
