Comparing Usha
and Wendy at first |
$154 more |
|
| Before |
8x4 =
32 u |
6x3 =
18 u |
| Change |
- 5x4 =
- 20 u |
- 5x3 =
- 15 u |
| After |
3x4 =
12 u |
1x3 =
3 u |
Comparing Usha
and Wendy in the end |
4x3 =
12 u |
1x3 =
3 u |
The amount that Usha had in the end is repeated. Make the amount that Usha had in the end the same. LCM of 4 and 3 is 12.
Amount that Usha had more than Wendy
= 32 u - 18 u
= 14 u
14 u = 154
1 u = 154 ÷ 14 = 11
Amount that Wendy had at first
= 18 u
= 18 x 11
= $198
Answer(s): $198
