Ben, Brandon and Zeph shared a sum of money. Ben and Brandon received 70% of the total amount of money. Brandon and Zeph received 50% of the total amount of money. Given that Brandon received $30 less than Ben, how much was the sum of money that was shared by Brandon and Zeph?

12 The total amount of money that Ben, Brandon and Zeph shared is repeated. Make the total amount of money the same. LCM of 10 and 2 is 10.
Amount that Brandon received less than Ben
= 5 u - 2 u
= 3 u
3 u = 30
1 u = 30 ÷ 3 = 10
Amount that Brandon and Zeph shared
= 2 u + 3 u
= 5 u
= 5 x 10
= $50
Answer(s): $50
