| After |
1x5 =
5 u |
1x5 =
5 u |
2x5 =
10 u |
1x2 =
2 u |
4x2 =
8 u |
5x2 =
10 u |
The total amount in both scenarios is the same. LCM of 2 and 5 is 10.
In both scenarios, Xavier had the same amount at first.
5 u + 6 = 2 u - 6
5 u - 2 u = 6 + 6
3 u = 12
1 u = 12 ÷ 3 = 4
Amount that Raeann has
= 5 u - 6
= 5 x 4 - 6
= $14
Answer(s): $14
