Dolly's share of spending --- $x
Emily's share of spending --- $(114.8-x)
If Dolly spent .4 of her money she has .6 of it left over
Dolly has left over: .6x
Emily has leftover : 114.8 - x - 30.8 = -x + 84
.6x = -x+84
1.6x = 84
x = 52.5
Dolly brought $52.50
Emily brought $62.30
check: is 52.5+62.3 = 114.8 ? YES
Dolly still has .6(52.5) or 31.50
Emily still has 62.3-30.8 = 31.5
all checks out!
