Perry, Albert, Justin and Cole shared $84. Cole received ²₅ of the total amount of money received by Perry, Albert and Justin. Perry received ¹₃ of the total amount for Albert and Justin. Albert received ²₃ as much money as Justin. If Justin gave all his money to Cole, how much did Cole have more than Albert in the end?

Perry	Albert	Justin	Cole	Total
5x4			2x4	7x4
1x5	3x5
	2x3	3x3
5 u	6 u	9 u	8 u	28 u

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

The total amount that Perry, Albert and Justin have is repeated.  Make the total amount of Perry, Albert and Justin the same. LCM of 20 and 5 is 20.

Total amount that Perry, Albert, Justin and Cole shared = 28 u

28 u = 84

1 u = 84 ÷ 28 = 3

	Perry	Albert	Justin	Cole
Before	5 u	6 u	9 u	8 u
Change			- 9 u	+ 9 u
After	5 u	6 u	0 u	17 u

Amount that Cole had if Justin gave him all his money
= 8 u + 9 u
= 17 u

Amount that Cole had more than Albert
= 17 u - 6 u
= 11 u
= 11 x 3
= $33

Answer(s): $33
