Ryan, Andy, Luke and Bryan shared $180. Bryan received ¹₄ of the total amount of money received by Ryan, Andy and Luke. Ryan received ³₅ of the total amount for Andy and Luke. Andy received ¹₂ as much money as Luke. If Andy gave all his money to Bryan, how much did Bryan have more than Ryan in the end?

Ryan	Andy	Luke	Bryan	Total
4x6			1x6	5x6
3x3	5x3
	1x5	2x5
9 u	5 u	10 u	6 u	30 u

The total amount that Andy and Luke have is repeated.  Make the total amount of Andy and Luke the same.  LCM of 3 and 5 is 15.

The total amount that Ryan, Andy and Luke have is repeated.  Make the total amount of Ryan, Andy and Luke the same. LCM of 24 and 4 is 24.

Total amount that Ryan, Andy, Luke and Bryan shared = 30 u

30 u = 180

1 u = 180 ÷ 30 = 6

	Ryan	Andy	Luke	Bryan
Before	9 u	5 u	10 u	6 u
Change		- 5 u		+ 5 u
After	9 u	0 u	10 u	11 u

Amount that Bryan had if Andy gave him all his money
= 6 u + 5 u
= 11 u

Amount that Bryan had more than Ryan
= 11 u - 9 u
= 2 u
= 2 x 6
= $12

Answer(s): $12
