Comparing Xandra
and Winnie at first |
$190 more |

| Before |
5x2 =
10 u |
5x1 =
5 u |
| Change |
- 3x2 =
- 6 u |
- 4x1 =
- 4 u |
| After |
2x2 =
4 u |
1x1 =
1 u |
Comparing Xandra
and Winnie in the end |
4x1 =
4 u |
1x1 =
1 u |
The amount that Xandra had in the end is repeated. Make the amount that Xandra had in the end the same. LCM of 4 and 2 is 4.
Amount that Xandra had more than Winnie
= 10 u - 5 u
= 5 u
5 u = 190
1 u = 190 ÷ 5 = 38
Amount that Winnie had at first
= 5 u
= 5 x 38
= $190
Answer(s): $190
