| Before |
8x4 =
32 u |
4x5 =
20 u |
| Change |
- 3x4 =
- 12 u |
- 3x5 =
- 15 u |
| After |
5x4 =
20 u |
1x5 =
5 u |
Comparing Shannon
and Julie in the end |
4x5 =
20 u |
1x5 =
5 u |
The amount that Shannon had in the end is repeated. Make the amount that Shannon had in the end the same. LCM of 4 and 5 is 20.
Amount that Julie had less than Shannon
= 32 u - 20 u
= 12 u
12 u = 372
1 u = 372 ÷ 12 = 31
Amount that Shannon had at first
= 32 u
= 32 x 31
= $992
Answer(s): $992
