Abner and Tommy had $160 altogether. Tommy had $48 less than Abner. After Tommy spent some money at the store, Abner had 4 times as much money as Tommy. How much money had Tommy spent at the store?

First , find out how much money they had to start

 

a       +      a-48       = 160

2a = 208

a = 104       then t =  56

 

the t spends some money and this is the result:

 

(56 - s) *4   =  104

224 - 4s = 104

-4s = -120

s = 30                       t   spent   $ 30 at the store
