Xuan and Penelope had the same amount of money at first. After Xuan gave $360 to her nephew, Penelope had 5 times as much money as Xuan. How much did Xuan have in the end?

Xuan |
Penelope |
| Before |
1x5 =
5 u |
1x5 =
5 u |
| Change |
- $360 |
|
| After |
1 u |
5 u |
The amount that Penelope had at first and in the end remains unchanged. Make the amount that Penelope had the same. LCM of 1 and 5 is 5.
Amount that Xuan gave to her nephew
= 5 u - 1 u
= 4 u
4 u = 360
1 u = 360 ÷ 4 = 90
Amount that Xuan had in the end
= 1 u
= $360
Answer(s): $360
