Question

Sherry spent 1/5 of her money on school supplies and 3/8 of the remainder on a CD player. She had $25 left. How much money did she have at first? ( PLEASE SHOW ALL STEPS)

Answer 1

common denominator- x/40
1x8= 8/40
3x5=15/40
15/40 + 8/40 = 23/40
25/40+23/40= 48/40

get rid of the denominator
48
