Yen and Esther had equal amount of money. Each day, Yen spent $14 and Esther spent $18. When Yen had $112 left, Esther had
12 as much money left as Yen. How much money did the two girls have at first?
| |
Yen |
Esther |
| Before |
14 u + 112 |
18 u + 56 |
| Change |
- 14 u |
- 18 u |
| After |
$112 |
$56 |
Amount that Esther had left
=
12 x 112
= $56
The amount that Yen and Esther had at first is the same.
18 u + 56 = 14 u + 112
18 u - 14 u = 112 - 56
4 u = 56
1 u = 56 ÷ 4 = 14
Amount that Yen had at first
= 14 u + 112
= 14 x 14 + 112
= 196 + 112
= $308
Total amount that both girls had at first
= 2 x 308
= $616
Answer(s): $616
