Chris spent 1/4 of his money to buy shirt .He spent 1/2 of remaining money to buy shorts.Given that Chris had left $56 left. How mush money did he at first?

he spend (1/4+1/2)=3/4 of his total money.
so has remaining money=(13/4)=1/4 of total money.
he had total money=$58*4=$432 
Let n be the amount Chris started with. After he spent 1/4, he had 3/4 n left. Then he spent 1/2 of that, leaving him with 1/2 of 3/4 n, or 3/8 n. So:
3n/8=56
3n=448
n=149.33333 as the amount Chris started with.
