Hilda and Anna had equal amount of money. Each day, Hilda spent $8 and Anna spent $17. When Hilda had $90 left, Anna had
35 as much money left as Hilda. How much money did the two girls have at first?

Hilda |
Anna |
| Before |
8 u + 90 |
17 u + 54 |
| Change |
- 8 u |
- 17 u |
| After |
$90 |
$54 |
Amount that Anna had left
=
35 x 90
= $54
The amount that Hilda and Anna had at first is the same.
17 u + 54 = 8 u + 90
17 u - 8 u = 90 - 54
9 u = 36
1 u = 36 ÷ 9 = 4
Amount that Hilda had at first
= 8 u + 90
= 8 x 4 + 90
= 32 + 90
= $122
Total amount that both girls had at first
= 2 x 122
= $244
Answer(s): $244
