Zane had $8.80 less than Michael. After Zane gave $1.80 to Michael, Michael would have five times as much money as Zane. How much money had Michael at first?

Michael |
Zane |
| Before |
5 u - $1.80 |
1 u + $1.80 |
| Change |
+ $1.80 |
- $1.80 |
| After |
5 u |
1 u |
Zane had $8.80 less than Michael. If another $8.80 was given to Zane, Michael and Zane would have the same amount at first.
5 u - 1.80 = 1 u + 1.80 + 8.80
5 u - 1 u = 1.80 + 8.80 + 1.80
4 u = 12.40
1 u = 12.40 ÷ 4 = 3.10
Amount that Michael had at first
= 5 u - 1.80
= 5 x 3.10 + 1.80
= 15.50 + 1.80
= $17.30
Answer(s): $17.30
