Comparing Min
and Kathy at first |
$374 more |
|
| Before |
8x4 =
32 u |
7x3 =
21 u |
| Change |
- 5x4 =
- 20 u |
- 6x3 =
- 18 u |
| After |
3x4 =
12 u |
1x3 =
3 u |
Comparing Min
and Kathy in the end |
4x3 =
12 u |
1x3 =
3 u |
The amount that Min had in the end is repeated. Make the amount that Min had in the end the same. LCM of 4 and 3 is 12.
Amount that Kathy had less than Min
= 32 u - 21 u
= 11 u
11 u = 374
1 u = 374 ÷ 11 = 34
Amount that Min had at first
= 32 u
= 32 x 34
= $1088
Answer(s): $1088
