Alyssa, Bert, and Cara are running for school president. Alyssa receives two-sevenths of the votes. Bert receives sixty-five percent of the remaining votes, and the rest of the votes go to Cara. If Cara receives 315 votes, how many votes were there in all?
Please help with step by step.

  • Math -

    number of votes --- x

    Alyssa gets (2/7)x
    leaving 5x/7

    Bert gets 65% of that or .65(5x/7)

    Cara gets x - 2x/7 - .65(5x/7)
    but that is 315

    x - 2x/7 - .65(5x/7) = 315
    times 7
    7x - 2x - .65(5x) = 315
    1.75x = 2205
    x = 1260 ----> number of votes


    check:
    Alyssa gets (2/7)1260 = 360
    leaving 900 votes
    Bert gets 65% of 900 = 585

    Carla gets 1260 - 360 - 585 = 315
    All is good!
