25 The total amount of money that Oscar, Ivan and Cole shared is repeated. Make the total amount of money the same. LCM of 4 and 5 is 20.
Amount that Oscar received more than Cole
= 12 u - 5 u
= 7 u
7 u = 42
1 u = 42 ÷ 7 = 6
Amount that Oscar and Cole shared
= 12 u + 5 u
= 17 u
= 17 x 6
= $102
Answer(s): $102
