The amount that George had remains unchanged. Make the amount that George had the same. LCM of 1 and 2 is 2.
Amount that Mark had in the end = 1 u
6 u - 85 = 1 u
6 u - 1 u = 85
5 u = 85
1 u = 85 ÷ 5 = 17
Amount that George had more than Bryan at first
= 6 u - 2 u
= 4 u
= 4 x 17
= $68
Answer(s): $68
