Jade and Vanessa had equal amount of money. Each day, Jade spent $8 and Vanessa spent $12. When Jade had $102 left, Vanessa had
13 as much money left as Jade. How much money did the two girls have at first?
| |
Jade |
Vanessa |
| Before |
8 u + 102 |
12 u + 34 |
| Change |
- 8 u |
- 12 u |
| After |
$102 |
$34 |
Amount that Vanessa had left
=
13 x 102
= $34
The amount that Jade and Vanessa had at first is the same.
12 u + 34 = 8 u + 102
12 u - 8 u = 102 - 34
4 u = 68
1 u = 68 ÷ 4 = 17
Amount that Jade had at first
= 8 u + 102
= 8 x 17 + 102
= 136 + 102
= $238
Total amount that both girls had at first
= 2 x 238
= $476
Answer(s): $476
