After |
5 u + 41 |
5 u + 41 |
6 u + 34 |
Amount that Xavier had in the end = 5 u + 41
Amount that Perry had in the end = 6 u + 34
Amount that Daniel had at first
= 5 u + 41 + 45 + 30
= 5 u + 116
Amount that Xavier and Perry had in the end is the same.
5 u + 41 = 6 u + 34
6 u - 5 u = 41 - 34
1 u = 7
Amount that Daniel and Xavier had in the end is the same.
Amount that Daniel had in the end
= 5 u + 41
= 5 x 7 + 41
= 35 + 41
= $76
Amount that Daniel had at first
= 76 + 45 + 30
= $151
Difference in the amounts between Daniel and Xavier at first
= 151 - 35
= $116
Answer(s): $116
