25 The total amount of money that Mark, Elijah and Will shared is repeated. Make the total amount of money the same. LCM of 4 and 5 is 20.
Amount that Elijah received less than Mark
= 12 u - 3 u
= 9 u
9 u = 108
1 u = 108 ÷ 9 = 12
Amount that Elijah and Will shared
= 3 u + 5 u
= 8 u
= 8 x 12
= $96
Answer(s): $96
