Ross' total --- x
Holly's amount = 60-x
after spending:
Holly has (3/4)(60-x)
Ross has x-5
given:
Holly/Ross = 1/2
(3/4)(60-x) / (x-5) = 1/2
45 - (3/4)x / (x-5) = 1/2
90 - (3/2)x = x - 5
180 - 3x = 2x - 10
190 = 5x
x = 38

h+r = 60
(3/4 h)/(r-5) = 1/2
now just find h and r.
Not sure just what the question is asking. More than when he ended, or more than Holly?
