14 The total amount of money that Andy, Albert and Justin shared is repeated. Make the total amount of money the same. LCM of 10 and 4 is 20.
Amount that Andy received more than Justin
= 15 u - 2 u
= 13 u
13 u = 156
1 u = 156 ÷ 13 = 12
Amount that Andy and Justin shared
= 15 u + 2 u
= 17 u
= 17 x 12
= $204
Answer(s): $204
