38 of his money, Ben had $89.60 more than Zeph. How much money did Ben have at first?

| Before |
8 u + $35.90 |
8 u |
$35.90 |
| Change |
|
- 3 u |
|
| After |
8 u + $35.90 |
5 u |
3 u + $35.90 |
Ben had $89.60 more than Zeph in the end.
8 u + 35.90 - 5 u = 89.60
3 u + 35.90 = 89.60
3 u = 89.60 - 35.90
3 u = 53.70
1 u = 53.70 ÷ 3 = 17.90
Amount that Ben had at first
= 8 u + 35.90
= 8 x 17.90 + 35.90
= 143.20 + 35.90
= $179.10
Answer(s): $179.10
