12 The total amount of money that Ahmad, Oliver and Vincent shared is repeated. Make the total amount of money the same. LCM of 10 and 2 is 10.
Amount that Oliver received less than Ahmad
= 5 u - 2 u
= 3 u
3 u = 30
1 u = 30 ÷ 3 = 10
Amount that Oliver and Vincent shared
= 2 u + 3 u
= 5 u
= 5 x 10
= $50
Answer(s): $50
