Total |
| Before |
2 u + 67 |
3 u + 41 |
113 |
| Change |
- 67 |
- 41 |

| After |
2 u |
3 u |

Amount that Henry had spent
= 67 - 26
= $41
Total amount that Billy and Henry had at first
= 2 u + 67 + 3 u + 41
= 5 u + 108
5 u + 108 = 113
5 u = 113 - 108
5 u = 5
1 u = 5 ÷ 5 = 1
Amount that Billy had at first
= 3 u + 67
= 3 x 1 + 67
= 3 + 67
= $70
Answer(s): $70
