Roshel, Tiffany, Abi and Sabrina received a sum of money. Roshel received ²₅ of the total amount of money Tiffany, Abi and Sabrina received. Tiffany received ¹₄ of the total amount of money Abi and Sabrina received. Abi received ¹₅ as much money as Sabrina. If Tiffany received $48 less than Roshel, find the total sum of money the 4 girls received.

Roshel	Tiffany	Abi	Sabrina	Total
2x3	5x3
	1x3	4x3
		1x2	5x2
6 u	3 u	2 u	10 u	21 u

The total amount that Abi and Sabrina have is repeated.  Make the total amount that Abi and Sabrina have the same.  LCM of 6 and 4 is 12.

The total amount that Tiffany, Abi and Sabrina have is repeated.  Make the total amount that Tiffany, Abi and Sabrina have the same. LCM of 5 and 5 is 15.

Amount that Tiffany had less than Roshel
= 6 u - 3 u
= 3 u

3 u = 48

1 u = 48 ÷ 3 = 16

Total sum of money that 4 girls received
= 6 u + 3 u + 2 u + 10 u 
= 21 u
= 21 x 16
= $336

Answer(s): $336
