| Before |
1 p + 3 u |
1 p + 1 u |
$100 |
| Change |
- 3 u |
- 1 u |

| After |
1 p |
1 p |

Amount that John spent more than Gabriel
= 3 u - 1 u
= 2 u
2 u = 100
1 u = 100 ÷ 2 = 50
Amount that John spent in 5 days
= 3 u
= 3 x 50
= $150
Amount that John spent every day
= 150 ÷ 5
= $30
Answer(s): $30
