Irene and Tina had equal amount of money. Each day, Irene spent $8 and Tina spent $10. When Irene had $92 left, Tina had
12 as much money left as Irene. How much money did the two girls have at first?

Irene |
Tina |
| Before |
8 u + 92 |
10 u + 46 |
| Change |
- 8 u |
- 10 u |
| After |
$92 |
$46 |
Amount that Tina had left
=
12 x 92
= $46
The amount that Irene and Tina had at first is the same.
10 u + 46 = 8 u + 92
10 u - 8 u = 92 - 46
2 u = 46
1 u = 46 ÷ 2 = 23
Amount that Irene had at first
= 8 u + 92
= 8 x 23 + 92
= 184 + 92
= $276
Total amount that both girls had at first
= 2 x 276
= $552
Answer(s): $552
