$192 more |
|
| Before |
8x3 =
24 u |
4x5 =
20 u |
| Change |
- 3x3 =
- 9 u |
- 3x5 =
- 15 u |
| After |
5x3 =
15 u |
1x5 =
5 u |
Comparing Esther
and Shiyun in the end |
3x5 =
15 u |
1x5 =
5 u |
The amount that Esther had in the end is repeated. Make the amount that Esther had in the end the same. LCM of 3 and 5 is 15.
Amount that Esther had more than Shiyun
= 24 u - 20 u
= 4 u
4 u = 192
1 u = 192 ÷ 4 = 48
Amount that Shiyun had at first
= 20 u
= 20 x 48
= $960
Answer(s): $960
