| Before |
7x4 =
28 u |
4x3 =
12 u |
| Change |
- 4x4 =
- 16 u |
- 3x3 =
- 9 u |
| After |
3x4 =
12 u |
1x3 =
3 u |
Comparing Winnie
and Sabrina in the end |
4x3 =
12 u |
1x3 =
3 u |
The amount that Winnie had in the end is repeated. Make the amount that Winnie had in the end the same. LCM of 4 and 3 is 12.
Amount that Sabrina had less than Winnie
= 28 u - 12 u
= 16 u
16 u = 736
1 u = 736 ÷ 16 = 46
Amount that Winnie had at first
= 28 u
= 28 x 46
= $1288
Answer(s): $1288
