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?

  • Maths -

    he spend (1/4+1/2)=3/4 of his total money.
    so has remaining money=(1-3/4)=1/4 of total money.
    he had total money=$58*4=$432

  • Maths -

    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.
