Comparing Jade
and Tiffany at first |
$105 more |
|
| Before |
5x2 =
10 u |
3x1 =
3 u |
| Change |
- 3x2 =
- 6 u |
- 2x1 =
- 2 u |
| After |
2x2 =
4 u |
1x1 =
1 u |
Comparing Jade
and Tiffany in the end |
4x1 =
4 u |
1x1 =
1 u |
The amount that Jade had in the end is repeated. Make the amount that Jade had in the end the same. LCM of 4 and 2 is 4.
Amount that Tiffany had less than Jade
= 10 u - 3 u
= 7 u
7 u = 105
1 u = 105 ÷ 7 = 15
Amount that Jade had at first
= 10 u
= 10 x 15
= $150
Answer(s): $150
