Usha and Shiyun had the same amount of money at first. After Usha gave $560 to her child, Shiyun had 8 times as much money as Usha. How much did Usha have in the end?

Usha |
Shiyun |
| Before |
1x8 =
8 u |
1x8 =
8 u |
| Change |
- $560 |
|
| After |
1 u |
8 u |
The amount that Shiyun had at first and in the end remains unchanged. Make the amount that Shiyun had the same. LCM of 1 and 8 is 8.
Amount that Usha gave to her child
= 8 u - 1 u
= 7 u
7 u = 560
1 u = 560 ÷ 7 = 80
Amount that Usha had in the end
= 1 u
= $560
Answer(s): $560
