Wendy and Risa had the same amount of money at first. After Wendy gave $50 to her child, Risa had 6 times as much money as Wendy. How much did Wendy have in the end?

Wendy |
Risa |
| Before |
1x6 =
6 u |
1x6 =
6 u |
| Change |
- $50 |
|
| After |
1 u |
6 u |
The amount that Risa had at first and in the end remains unchanged. Make the amount that Risa had the same. LCM of 1 and 6 is 6.
Amount that Wendy gave to her child
= 6 u - 1 u
= 5 u
5 u = 50
1 u = 50 ÷ 5 = 10
Amount that Wendy had in the end
= 1 u
= $50
Answer(s): $50
