After |
5 u + 49 |
5 u + 49 |
6 u + 35 |
Amount that Rael had in the end = 5 u + 49
Amount that Jack had in the end = 6 u + 35
Amount that Pierre had at first
= 5 u + 49 + 54 + 30
= 5 u + 133
Amount that Rael and Jack had in the end is the same.
5 u + 49 = 6 u + 35
6 u - 5 u = 49 - 35
1 u = 14
Amount that Pierre and Rael had in the end is the same.
Amount that Pierre had in the end
= 5 u + 49
= 5 x 14 + 49
= 70 + 49
= $119
Amount that Pierre had at first
= 119 + 54 + 30
= $203
Difference in the amounts between Pierre and Rael at first
= 203 - 70
= $133
Answer(s): $133
