Jason spent 3/8 of his money on a pair of shoes and 4/7 of the remainder on shirt. He found that he had $45 left. What was was his original amount of money?

x = origianl amount

 

spending 3/8 ths leaves  5/8 x        spending 4/7 of this leaves   3/7  (5/8 x)   and this = 45

 

3/7 ( 5/8 x) = 45    solve for x

x = 168

3/8

 

8 - 3 =5

 

 

1 - 4/7= 3/7

 

shirt = 4/7

 

left = 3/7 * 5x

      = 15x/7

 

15x/7 = $45

15x = $45 * 7

       = 315 ÷ 15

       = 21

orignal money = 8x

                        = 8 * 21

                        = $168
