| Before |
8x4 =
32 u |
4x5 =
20 u |
| Change |
- 3x4 =
- 12 u |
- 3x5 =
- 15 u |
| After |
5x4 =
20 u |
1x5 =
5 u |
Comparing Lynn
and Sabrina in the end |
4x5 =
20 u |
1x5 =
5 u |
The amount that Lynn had in the end is repeated. Make the amount that Lynn had in the end the same. LCM of 4 and 5 is 20.
Amount that Lynn had more than Sabrina
= 32 u - 20 u
= 12 u
12 u = 288
1 u = 288 ÷ 12 = 24
Amount that Sabrina had at first
= 20 u
= 20 x 24
= $480
Answer(s): $480
