Gabby and Dana had the same amount of money at first. After Gabby gave $60 to her nephew, Dana had 3 times as much money as Gabby. How much did Gabby have in the end?

Gabby |
Dana |
| Before |
1x3 =
3 u |
1x3 =
3 u |
| Change |
- $60 |
|
| After |
1 u |
3 u |
The amount that Dana had at first and in the end remains unchanged. Make the amount that Dana had the same. LCM of 1 and 3 is 3.
Amount that Gabby gave to her nephew
= 3 u - 1 u
= 2 u
2 u = 60
1 u = 60 ÷ 2 = 30
Amount that Gabby had in the end
= 1 u
= $60
Answer(s): $60
