Jean and Shiyun had equal amount of money. Each day, Jean spent $14 and Shiyun spent $17. When Jean had $80 left, Shiyun had
25 as much money left as Jean. How much money did the two girls have at first?
| |
Jean |
Shiyun |
| Before |
14 u + 80 |
17 u + 32 |
| Change |
- 14 u |
- 17 u |
| After |
$80 |
$32 |
Amount that Shiyun had left
=
25 x 80
= $32
The amount that Jean and Shiyun had at first is the same.
17 u + 32 = 14 u + 80
17 u - 14 u = 80 - 32
3 u = 48
1 u = 48 ÷ 3 = 16
Amount that Jean had at first
= 14 u + 80
= 14 x 16 + 80
= 224 + 80
= $304
Total amount that both girls had at first
= 2 x 304
= $608
Answer(s): $608
