Comparing Jaslyn
and Esther at first |
$170 more |
|
| Before |
7x2 =
14 u |
3x3 =
9 u |
| Change |
- 4x2 =
- 8 u |
- 2x3 =
- 6 u |
| After |
3x2 =
6 u |
1x3 =
3 u |
Comparing Jaslyn
and Esther in the end |
2x3 =
6 u |
1x3 =
3 u |
The amount that Jaslyn had in the end is repeated. Make the amount that Jaslyn had in the end the same. LCM of 2 and 3 is 6.
Amount that Esther had less than Jaslyn
= 14 u - 9 u
= 5 u
5 u = 170
1 u = 170 ÷ 5 = 34
Amount that Jaslyn had at first
= 14 u
= 14 x 34
= $476
Answer(s): $476
