Comparing Rachel
and Lynn at first |
$98 more |
|
| Before |
8x2 =
16 u |
3x3 =
9 u |
| Change |
- 5x2 =
- 10 u |
- 2x3 =
- 6 u |
| After |
3x2 =
6 u |
1x3 =
3 u |
Comparing Rachel
and Lynn in the end |
2x3 =
6 u |
1x3 =
3 u |
The amount that Rachel had in the end is repeated. Make the amount that Rachel had in the end the same. LCM of 2 and 3 is 6.
Amount that Lynn had less than Rachel
= 16 u - 9 u
= 7 u
7 u = 98
1 u = 98 ÷ 7 = 14
Amount that Rachel had at first
= 16 u
= 16 x 14
= $224
Answer(s): $224
