Comparing Elyse
and Nicole at first |
$423 more |
|
| Before |
5x3 =
15 u |
3x2 =
6 u |
| Change |
- 3x3 =
- 9 u |
- 2x2 =
- 4 u |
| After |
2x3 =
6 u |
1x2 =
2 u |
Comparing Elyse
and Nicole in the end |
3x2 =
6 u |
1x2 =
2 u |
The amount that Elyse had in the end is repeated. Make the amount that Elyse had in the end the same. LCM of 3 and 2 is 6.
Amount that Elyse had more than Nicole
= 15 u - 6 u
= 9 u
9 u = 423
1 u = 423 ÷ 9 = 47
Amount that Nicole had at first
= 6 u
= 6 x 47
= $282
Answer(s): $282
