Gwen and Xylia had the same amount of money at first. After Gwen gave $70 to her son, Xylia had 8 times as much money as Gwen. How much did Gwen have in the end?

| Before |
1x8 =
8 u |
1x8 =
8 u |
| Change |
- $70 |

| After |
1 u |
8 u |
The amount that Xylia had at first and in the end remains unchanged. Make the amount that Xylia had the same. LCM of 1 and 8 is 8.
Amount that Gwen gave to her son
= 8 u - 1 u
= 7 u
7 u = 70
1 u = 70 ÷ 7 = 10
Amount that Gwen had in the end
= 1 u
= $70
Answer(s): $70
