on saturday you earn half as much as you do on sunday but twice as much as you do on friday. during the 3 days you $70. how much did you earn each day

  • math -

    x = friday
    2x = saturday
    2(2x) = 4x = Sunday

    1x+2x+4x = 7x

    7x = 70
    x = 10 friday
    2x = 20 = saturday
    4x = 40 = sunday

  • math -

    Assuming you earn a total of $70.
    x = amt earned Sat
    2x = amt earned Sun
    1/2 x = amt earned Fri

    x + 2x + 1/2 x = 70

    Solve for x
