Kylie and Julie had the same amount of money at first. After Kylie gave $150 to her cousin, Julie had 4 times as much money as Kylie. How much did Kylie have in the end?

Kylie |
Julie |
| Before |
1x4 =
4 u |
1x4 =
4 u |
| Change |
- $150 |

| After |
1 u |
4 u |
The amount that Julie had at first and in the end remains unchanged. Make the amount that Julie had the same. LCM of 1 and 4 is 4.
Amount that Kylie gave to her cousin
= 4 u - 1 u
= 3 u
3 u = 150
1 u = 150 ÷ 3 = 50
Amount that Kylie had in the end
= 1 u
= $150
Answer(s): $150
