Rex spent $105 on a wallet and 2/5 of his remaining money on a T-shirt. He then had 1/3 of the total amount of money left. How much did the T-shirt cost?

x = starting amount

 

x - 105     amount after wallet

 

3/5 (x-105)     amount after t shirt     and this equals 1/3 x        

 

 

3/5 (x-105) = 1/3 x

4/15x = 63

x = 236.25

 

 

2/5 ( 236.25 - 105) =  52.50    <==== shirt price
