Wendy, Roshel, Lynn and Betty received a sum of money. Wendy received ²₅ of the total amount of money Roshel, Lynn and Betty received. Roshel received ¹₄ of the total amount of money Lynn and Betty received. Lynn received ¹₅ as much money as Betty. If Roshel received $60 less than Wendy, find the total sum of money the 4 girls received.

Wendy	Roshel	Lynn	Betty	Total
2x3	5x3
	1x3	4x3
		1x2	5x2
6 u	3 u	2 u	10 u	21 u

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

The total amount that Roshel, Lynn and Betty have is repeated.  Make the total amount that Roshel, Lynn and Betty have the same. LCM of 5 and 5 is 15.

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

3 u = 60

1 u = 60 ÷ 3 = 20

Total sum of money that 4 girls received
= 6 u + 3 u + 2 u + 10 u 
= 21 u
= 21 x 20
= $420

Answer(s): $420
