    Answer:$20 = Charlie, $60 = Josh, $10 = Melissa

    Step-by-step explanation:

    M+C+J=90 = Melissa, Charlie, and Josh have a total of $90 in their wallets

    J=3C = Josh has 3 times what Charlie has

    M=C-10 = Melissa has $10 less than Charlie.

    Therefore

    M+C+J=90

    (C-10) + C + 3C=90

    5C-10=90

    5C=100

    C=20 = Charlie

    J=3C = 60 = Josh

    M=C-10 = 10 = Melissa
