Jaslyn, Zoe, Sabrina and Nora received a sum of money. Jaslyn received ⁵₈ of the total amount of money Zoe, Sabrina and Nora received. Zoe received ¹₃ of the total amount of money Sabrina and Nora received. Sabrina received ¹₅ as much money as Nora. If Jaslyn received $40 more than Sabrina, find the total sum of money the 4 girls received.

Jaslyn	Zoe	Sabrina	Nora	Total
5x1	8x1
	1x2	3x2
		1x1	5x1
5 u	2 u	1 u	5 u	13 u

The total amount that Sabrina and Nora have is repeated.  Make the total amount that Sabrina and Nora have the same.  LCM of 6 and 3 is 6.

The total amount that Zoe, Sabrina and Nora have is repeated.  Make the total amount that Zoe, Sabrina and Nora have the same. LCM of 4 and 8 is 8.

Amount that Jaslyn had more than Sabrina
= 5 u - 1 u
= 4 u

4 u = 40

1 u = 40 ÷ 4 = 10

Total sum of money that 4 girls received
= 5 u + 2 u + 1 u + 5 u 
= 13 u
= 13 x 10
= $130

Answer(s): $130
