- 3x1 =
- 3 u |
| After |
1x2 =
2 u |
1x1 =
1 u |
The amount that Justin and Gem had at first is the same. Make the amount that Justin and Gem had at first the same. LCM of 2 and 4 is 4.
Amount that Gem spent more than Justin
= 3 u - 2 u
= 1 u
1 u = 7
Amount that Justin had at first
= 4 u
= 4 x 7
= $28
Answer(s): $28
