Victoria and Emma had equal amount of money. Each day, Victoria spent $4 and Emma spent $6. When Victoria had $108 left, Emma had
16 as much money left as Victoria. How much money did the two girls have at first?

Victoria |
Emma |
| Before |
4 u + 108 |
6 u + 18 |
| Change |
- 4 u |
- 6 u |
| After |
$108 |
$18 |
Amount that Emma had left
=
16 x 108
= $18
The amount that Victoria and Emma had at first is the same.
6 u + 18 = 4 u + 108
6 u - 4 u = 108 - 18
2 u = 90
1 u = 90 ÷ 2 = 45
Amount that Victoria had at first
= 4 u + 108
= 4 x 45 + 108
= 180 + 108
= $288
Total amount that both girls had at first
= 2 x 288
= $576
Answer(s): $576
