Lucy and Shannon had the same amount of money at first. After Lucy gave $150 to her daughter, Shannon had 6 times as much money as Lucy. How much did Lucy have in the end?

Lucy |
Shannon |
| Before |
1x6 =
6 u |
1x6 =
6 u |
| Change |
- $150 |
|
| After |
1 u |
6 u |
The amount that Shannon had at first and in the end remains unchanged. Make the amount that Shannon had the same. LCM of 1 and 6 is 6.
Amount that Lucy gave to her daughter
= 6 u - 1 u
= 5 u
5 u = 150
1 u = 150 ÷ 5 = 30
Amount that Lucy had in the end
= 1 u
= $150
Answer(s): $150
