Perry and Rachel had equal amount of money. Perry spent
12 of his money on a blazer while Rachel spent
23 of her money on a windbreaker. Given that Rachel spent $18 more than Perry, how much did Perry have at first?

Perry |
Rachel |
Before |
2x3 = 6 u |
3x2 = 6 u |
Change |
- 1x3 = - 3 u |
- 2x2 = - 4 u |
After |
1x3 = 3 u |
1x2 = 2 u |
The amount that Perry and Rachel had at first is the same. Make the amount that Perry and Rachel had at first the same. LCM of 2 and 3 is 6.
Amount that Rachel spent more than Perry
= 4 u - 3 u
= 1 u
1 u = 18
Amount that Perry had at first
= 6 u
= 6 x 18
= $108
Answer(s): $108
