Xuan and Jean had equal amount of money. Each day, Xuan spent $16 and Jean spent $24. When Xuan had $112 left, Jean had
27 as much money left as Xuan. How much money did the two girls have at first?
| |
Xuan |
Jean |
| Before |
16 u + 112 |
24 u + 32 |
| Change |
- 16 u |
- 24 u |
| After |
$112 |
$32 |
Amount that Jean had left
=
27 x 112
= $32
The amount that Xuan and Jean had at first is the same.
24 u + 32 = 16 u + 112
24 u - 16 u = 112 - 32
8 u = 80
1 u = 80 ÷ 8 = 10
Amount that Xuan had at first
= 16 u + 112
= 16 x 10 + 112
= 160 + 112
= $272
Total amount that both girls had at first
= 2 x 272
= $544
Answer(s): $544
