Rachel and Min had equal amount of money. Each day, Rachel spent $20 and Min spent $26. When Rachel had $105 left, Min had
35 as much money left as Rachel. How much money did the two girls have at first?
| |
Rachel |
Min |
| Before |
20 u + 105 |
26 u + 63 |
| Change |
- 20 u |
- 26 u |
| After |
$105 |
$63 |
Amount that Min had left
=
35 x 105
= $63
The amount that Rachel and Min had at first is the same.
26 u + 63 = 20 u + 105
26 u - 20 u = 105 - 63
6 u = 42
1 u = 42 ÷ 6 = 7
Amount that Rachel had at first
= 20 u + 105
= 20 x 7 + 105
= 140 + 105
= $245
Total amount that both girls had at first
= 2 x 245
= $490
Answer(s): $490
