| Before |
3 u + 40 |
5 u + 30 |
102 |
| Change |
- 40 |
- 30 |

| After |
3 u |
5 u |

Amount that John had spent
= 40 - 10
= $30
Total amount that Henry and John had at first
= 3 u + 40 + 5 u + 30
= 8 u + 70
8 u + 70 = 102
8 u = 102 - 70
8 u = 32
1 u = 32 ÷ 8 = 4
Amount that Henry had at first
= 5 u + 40
= 5 x 4 + 40
= 20 + 40
= $60
Answer(s): $60
