12 The total amount of money that Ken, Ethan and Brandon shared is repeated. Make the total amount of money the same. LCM of 5 and 2 is 10.
Amount that Ken received more than Brandon
= 5 u - 2 u
= 3 u
3 u = 57
1 u = 57 ÷ 3 = 19
Amount that Ken and Brandon shared
= 5 u + 2 u
= 7 u
= 7 x 19
= $133
Answer(s): $133
