$84 more |
|
| Before |
8x4 =
32 u |
6x5 =
30 u |
| Change |
- 3x4 =
- 12 u |
- 5x5 =
- 25 u |
| After |
5x4 =
20 u |
1x5 =
5 u |
Comparing Joelle
and Julie in the end |
4x5 =
20 u |
1x5 =
5 u |
The amount that Joelle had in the end is repeated. Make the amount that Joelle had in the end the same. LCM of 4 and 5 is 20.
Amount that Joelle had more than Julie
= 32 u - 30 u
= 2 u
2 u = 84
1 u = 84 ÷ 2 = 42
Amount that Julie had at first
= 30 u
= 30 x 42
= $1260
Answer(s): $1260
