The amount that Albert had remains unchanged. Make the amount that Albert had the same. LCM of 1 and 3 is 3.
Amount that Mark had in the end = 1 u
24 u - 69 = 1 u
24 u - 1 u = 69
23 u = 69
1 u = 69 ÷ 23 = 3
Amount that Albert had more than Howard at first
= 24 u - 3 u
= 21 u
= 21 x 3
= $63
Answer(s): $63
