Eva and Sarah had the same amount of money at first. After Eva gave $140 to her nephew, Sarah had 8 times as much money as Eva. How much did Eva have in the end?

| Before |
1x8 =
8 u |
1x8 =
8 u |
| Change |
- $140 |

| After |
1 u |
8 u |
The amount that Sarah had at first and in the end remains unchanged. Make the amount that Sarah had the same. LCM of 1 and 8 is 8.
Amount that Eva gave to her nephew
= 8 u - 1 u
= 7 u
7 u = 140
1 u = 140 ÷ 7 = 20
Amount that Eva had in the end
= 1 u
= $140
Answer(s): $140
