14 The total amount of money that Pierre, Peter and Warren shared is repeated. Make the total amount of money the same. LCM of 10 and 4 is 20.
Amount that Peter received less than Pierre
= 15 u - 3 u
= 12 u
12 u = 72
1 u = 72 ÷ 12 = 6
Amount that Peter and Warren shared
= 3 u + 2 u
= 5 u
= 5 x 6
= $30
Answer(s): $30
