Total |
| Before |
2 u + 30 |
3 u + 18 |
133 |
| Change |
- 30 |
- 18 |
|
| After |
2 u |
3 u |

Amount that Rael had spent
= 30 - 12
= $18
Total amount that Charlie and Rael had at first
= 2 u + 30 + 3 u + 18
= 5 u + 48
5 u + 48 = 133
5 u = 133 - 48
5 u = 85
1 u = 85 ÷ 5 = 17
Amount that Charlie had at first
= 3 u + 30
= 3 x 17 + 30
= 51 + 30
= $81
Answer(s): $81
