25 The total amount of money that Archie, Zeph and Oscar shared is repeated. Make the total amount of money the same. LCM of 4 and 5 is 20.
Amount that Archie received more than Oscar
= 12 u - 5 u
= 7 u
7 u = 49
1 u = 49 ÷ 7 = 7
Amount that Archie and Oscar shared
= 12 u + 5 u
= 17 u
= 17 x 7
= $119
Answer(s): $119
