Shannon and Eva had the same amount of money at first. After Shannon gave $540 to her nephew, Eva had 7 times as much money as Shannon. How much did Shannon have in the end?

| Before |
1x7 =
7 u |
1x7 =
7 u |
| Change |
- $540 |

| After |
1 u |
7 u |
The amount that Eva had at first and in the end remains unchanged. Make the amount that Eva had the same. LCM of 1 and 7 is 7.
Amount that Shannon gave to her nephew
= 7 u - 1 u
= 6 u
6 u = 540
1 u = 540 ÷ 6 = 90
Amount that Shannon had in the end
= 1 u
= $540
Answer(s): $540
