12 of his money on a shirt while Penelope spent
23 of her money on a jumpsuit. Given that Penelope spent $15 more than Jack, how much did Jack have at first?

Jack |
Penelope |
| Before |
2x3 =
6 u |
3x2 =
6 u |
| Change |
- 1x3 =
- 3 u |
- 2x2 =
- 4 u |
| After |
1x3 =
3 u |
1x2 =
2 u |
The amount that Jack and Penelope had at first is the same. Make the amount that Jack and Penelope had at first the same. LCM of 2 and 3 is 6.
Amount that Penelope spent more than Jack
= 4 u - 3 u
= 1 u
1 u = 15
Amount that Jack had at first
= 6 u
= 6 x 15
= $90
Answer(s): $90
