$195 more |
|
| Before |
7x3 =
21 u |
4x4 =
16 u |
| Change |
- 3x3 =
- 9 u |
- 3x4 =
- 12 u |
| After |
4x3 =
12 u |
1x4 =
4 u |
Comparing Min
and Natalie in the end |
3x4 =
12 u |
1x4 =
4 u |
The amount that Min had in the end is repeated. Make the amount that Min had in the end the same. LCM of 3 and 4 is 12.
Amount that Min had more than Natalie
= 21 u - 16 u
= 5 u
5 u = 195
1 u = 195 ÷ 5 = 39
Amount that Natalie had at first
= 16 u
= 16 x 39
= $624
Answer(s): $624
