Comparing Jane
and Lynn at first |
$192 more |
|
| Before |
8x4 =
32 u |
8x3 =
24 u |
| Change |
- 5x4 =
- 20 u |
- 7x3 =
- 21 u |
| After |
3x4 =
12 u |
1x3 =
3 u |
Comparing Jane
and Lynn in the end |
4x3 =
12 u |
1x3 =
3 u |
The amount that Jane had in the end is repeated. Make the amount that Jane had in the end the same. LCM of 4 and 3 is 12.
Amount that Jane had more than Lynn
= 32 u - 24 u
= 8 u
8 u = 192
1 u = 192 ÷ 8 = 24
Amount that Lynn had at first
= 24 u
= 24 x 24
= $576
Answer(s): $576
