Comparing Rachel
and Kylie at first |
$185 more |
|
| Before |
5x3 =
15 u |
5x2 =
10 u |
| Change |
- 3x3 =
- 9 u |
- 4x2 =
- 8 u |
| After |
2x3 =
6 u |
1x2 =
2 u |
Comparing Rachel
and Kylie in the end |
3x2 =
6 u |
1x2 =
2 u |
The amount that Rachel had in the end is repeated. Make the amount that Rachel had in the end the same. LCM of 3 and 2 is 6.
Amount that Kylie had less than Rachel
= 15 u - 10 u
= 5 u
5 u = 185
1 u = 185 ÷ 5 = 37
Amount that Rachel had at first
= 15 u
= 15 x 37
= $555
Answer(s): $555
