Sabrina and Min had the same amount of money at first. After Sabrina gave $120 to her cousin, Min had 5 times as much money as Sabrina. How much did Sabrina have in the end?

Sabrina |
Min |
| Before |
1x5 =
5 u |
1x5 =
5 u |
| Change |
- $120 |

| After |
1 u |
5 u |
The amount that Min had at first and in the end remains unchanged. Make the amount that Min had the same. LCM of 1 and 5 is 5.
Amount that Sabrina gave to her cousin
= 5 u - 1 u
= 4 u
4 u = 120
1 u = 120 ÷ 4 = 30
Amount that Sabrina had in the end
= 1 u
= $120
Answer(s): $120
