Question

Can you spend 1/5 of his allowance on a movie 3/8 on snacks and 2/7 on games if his allowance was $20 how much did Ken have

1 Answer

  • For this case we assume that the initial amount of money is $20.

    So:

    • [tex]\frac{1} {5}[/tex] of $20 in movies:

    [tex]\frac {1} {5} (20) = 4[/tex]

    • [tex]\frac {3} {8}[/tex] of $20 in snacks:

    [tex]\frac {3} {8} (20) = 7.5[/tex]

    • [tex]\frac {2} {7}[/tex] of $20 in games:

    [tex]\frac {2} {7} (20) = 5.71[/tex]

    Adding we have:

    [tex]4 + 7.5 + 5.71 = 17.21[/tex]

    Ken has:

    [tex]20-17.21 = 2.79[/tex]

    Answer:

    Ken can spend what he planned and he has $2.79 left.
