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)

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
