Jane |
| Before |
2x5 =
10 u |
5x2 =
10 u |
| Change |
- 1x5 =
- 5 u |
- 3x2 =
- 6 u |
| After |
1x5 =
5 u |
2x2 =
4 u |
The amount that Luis and Jane had at first is the same. Make the amount that Luis and Jane had at first the same. LCM of 2 and 5 is 10.
Amount that Jane spent more than Luis
= 6 u - 5 u
= 1 u
1 u = 18
Amount that Luis had at first
= 10 u
= 10 x 18
= $180
Answer(s): $180
