| After |
9 u + $59.10 |
4 u |
5 u + $59.10 |
Sean had $141.60 more than Bobby in the end.
9 u + 59.10 - 4 u = 141.60
5 u + 59.10 = 141.60
5 u = 141.60 - 59.10
5 u = 82.50
1 u = 82.50 ÷ 5 = 16.50
Amount that Sean had at first
= 9 u + 59.10
= 9 x 16.50 + 59.10
= 148.50 + 59.10
= $207.60
Answer(s): $207.60
