Question

A music store marks up the instruments it sells by 30%.

a. If the store bought a guitar for 45$ what will be its store price?
b. If the price tag on a trumpet says 104$ how much did the store pay for it?

Answer 1

a. $45/100 = 0.45
0.45 x 130 = $58.50
Guitar S.P = $58.50

b. $104/130 = 0.80
0.80 x 100 = $80
Store paid: $80
