25 The total amount of money that Brandon, Cole and Oscar shared is repeated. Make the total amount of money the same. LCM of 10 and 5 is 10.
Amount that Brandon received more than Oscar
= 6 u - 1 u
= 5 u
5 u = 75
1 u = 75 ÷ 5 = 15
Amount that Brandon and Oscar shared
= 6 u + 1 u
= 7 u
= 7 x 15
= $105
Answer(s): $105
