    Exclamation Percentage question #5

    Sandy has 50% more money than Bradon. Bradon has 20% more money than Clement. After Sandy gives Bradon and Clement a total of $350 and Bradon gives Clement $400, the ratio of Sandy's money to Bradon's moneey to Clement's money becomes 1:1:3. How much money did Sandy give to Bradon?

    Since Bradon is defined in terms of Clement and Sandy is defined in terms of Bradon, pick a variable for Clement, and work from there.

    start:
    Clement: c
    Bradon: 1.2c
    Sandy: 1.5(1.2c) = 1.8c

    changes:
    Sandy: 1.8c - 350
    Bradon: 1.2c - 400 + s
    Clement: c + 400 + (350 - s) = c + 750 - s

    end:
    (1.8c - 350) : (1.2c - 400 + s) : (c + 750 - s) = 1 : 1 : 3

    Then:

    1.8c - 350 = 1.2c - 400 + s

    ...and:

    3(1.8c - 350) = c + 750 - s

    Solve the resulting system of equations.
