- 3x1 =
- 3 u |
| After |
1x2 =
2 u |
1x1 =
1 u |
The amount that John and Vanessa had at first is the same. Make the amount that John and Vanessa had at first the same. LCM of 2 and 4 is 4.
Amount that Vanessa spent more than John
= 3 u - 2 u
= 1 u
1 u = 3
Amount that John had at first
= 4 u
= 4 x 3
= $12
Answer(s): $12
