After |
4 u + 37 |
4 u + 37 |
5 u + 29 |
Amount that Ken had in the end = 4 u + 37
Amount that Elijah had in the end = 5 u + 29
Amount that Vincent had at first
= 4 u + 37 + 41 + 25
= 4 u + 103
Amount that Ken and Elijah had in the end is the same.
4 u + 37 = 5 u + 29
5 u - 4 u = 37 - 29
1 u = 8
Amount that Vincent and Ken had in the end is the same.
Amount that Vincent had in the end
= 4 u + 37
= 4 x 8 + 37
= 32 + 37
= $69
Amount that Vincent had at first
= 69 + 41 + 25
= $135
Difference in the amounts between Vincent and Ken at first
= 135 - 32
= $103
Answer(s): $103
