38 of her money and Jen spent
45 of her money. In the end, Min had 4 times as much as Jen. Find the amount of money Jen had at first.

Comparing Min
and Jen at first |
$203 more |
|
| Before |
8x4 =
32 u |
5x5 =
25 u |
| Change |
- 3x4 =
- 12 u |
- 4x5 =
- 20 u |
| After |
5x4 =
20 u |
1x5 =
5 u |
Comparing Min
and Jen in the end |
4x5 =
20 u |
1x5 =
5 u |
The amount that Min had in the end is repeated. Make the amount that Min had in the end the same. LCM of 4 and 5 is 20.
Amount that Min had more than Jen
= 32 u - 25 u
= 7 u
7 u = 203
1 u = 203 ÷ 7 = 29
Amount that Jen had at first
= 25 u
= 25 x 29
= $725
Answer(s): $725
