The amount that Albert had remains unchanged. Make the amount that Albert had the same. LCM of 1 and 2 is 2.
Amount that Mark had in the end = 1 u
10 u - 63 = 1 u
10 u - 1 u = 63
9 u = 63
1 u = 63 ÷ 9 = 7
Amount that Albert had more than Seth at first
= 10 u - 2 u
= 8 u
= 8 x 7
= $56
Answer(s): $56
