Gwen and Lucy had equal amount of money. Each day, Gwen spent $17 and Lucy spent $20. When Gwen had $88 left, Lucy had
14 as much money left as Gwen. How much money did the two girls have at first?

Gwen |
Lucy |
| Before |
17 u + 88 |
20 u + 22 |
| Change |
- 17 u |
- 20 u |
| After |
$88 |
$22 |
Amount that Lucy had left
=
14 x 88
= $22
The amount that Gwen and Lucy had at first is the same.
20 u + 22 = 17 u + 88
20 u - 17 u = 88 - 22
3 u = 66
1 u = 66 ÷ 3 = 22
Amount that Gwen had at first
= 17 u + 88
= 17 x 22 + 88
= 374 + 88
= $462
Total amount that both girls had at first
= 2 x 462
= $924
Answer(s): $924
