Austin and Kaitlyn Kojan invested $195,000 in a business venture. If Kaitlyn invested 2 ¼ times as much as Austin invested, how much money did Kaitlyn invest? (Points : 2)

  • algebra -

    amount invested by Austin --- x
    amount invested by Kaitlyn --- 2 ¼(x) = 9x/4

    x + 9x/4 = 195000
    4x + 9x = 780000
    13x = 780000
    x = 60000

    Kaitlyn --- (9/4)(60000) = 135000

    check: 135000/60000 = 2.25 or 9/4
