14 The total amount of money that Billy, Japheth and Peter shared is repeated. Make the total amount of money the same. LCM of 10 and 4 is 20.
Amount that Billy received more than Peter
= 15 u - 2 u
= 13 u
13 u = 65
1 u = 65 ÷ 13 = 5
Amount that Billy and Peter shared
= 15 u + 2 u
= 17 u
= 17 x 5
= $85
Answer(s): $85
