    Fri. $10

    Sat. $40

    Sun. $20

    Step-by-step explanation:

    earnings on Saturday=x

    Sunday is. 5*x, which is 1/2 of Saturday

    Friday is. 25*x, which is 1/2 of Sunday

    x+.5x+.25x=70

    (simplify) 1.75x=70

    Divide by 1.75 1.75x/1.75=70/1.75

    X=40

    then plug in x for all days
