Comparing Xylia
and Winnie at first |
$340 more |
|
| Before |
8x4 =
32 u |
5x3 =
15 u |
| Change |
- 5x4 =
- 20 u |
- 4x3 =
- 12 u |
| After |
3x4 =
12 u |
1x3 =
3 u |
Comparing Xylia
and Winnie in the end |
4x3 =
12 u |
1x3 =
3 u |
The amount that Xylia had in the end is repeated. Make the amount that Xylia had in the end the same. LCM of 4 and 3 is 12.
Amount that Winnie had less than Xylia
= 32 u - 15 u
= 17 u
17 u = 340
1 u = 340 ÷ 17 = 20
Amount that Xylia had at first
= 32 u
= 32 x 20
= $640
Answer(s): $640
