Dolly and Emily went shopping with a total of $114.80. After Dolly spent 0.4 of her money and Emily spent $30.80, they had an equal amount of money left. How much money didi Emily bring along for shopping?

Answer 1

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!
