Wendy and Ivory had the same amount of money at first. After Wendy gave $200 to her daughter, Ivory had 3 times as much money as Wendy. How much did Wendy have in the end?

Wendy |
Ivory |
| Before |
1x3 =
3 u |
1x3 =
3 u |
| Change |
- $200 |
|
| After |
1 u |
3 u |
The amount that Ivory had at first and in the end remains unchanged. Make the amount that Ivory had the same. LCM of 1 and 3 is 3.
Amount that Wendy gave to her daughter
= 3 u - 1 u
= 2 u
2 u = 200
1 u = 200 ÷ 2 = 100
Amount that Wendy had in the end
= 1 u
= $200
Answer(s): $200
