Sarah, Min, Joelle and Tina received a sum of money. Sarah received ⁵₈ of the total amount of money Min, Joelle and Tina received. Min received ¹₅ of the total amount of money Joelle and Tina received. Joelle received ¹₃ as much money as Tina. If Min received $66 less than Sarah, find the total sum of money the 4 girls received.

Sarah	Min	Joelle	Tina	Total
5x3	8x3
	1x4	5x4
		1x5	3x5
15 u	4 u	5 u	15 u	39 u

The total amount that Joelle and Tina have is repeated.  Make the total amount that Joelle and Tina have the same.  LCM of 4 and 5 is 20.

The total amount that Min, Joelle and Tina have is repeated.  Make the total amount that Min, Joelle and Tina have the same. LCM of 6 and 8 is 24.

Amount that Min had less than Sarah
= 15 u - 4 u
= 11 u

11 u = 66

1 u = 66 ÷ 11 = 6

Total sum of money that 4 girls received
= 15 u + 4 u + 5 u + 15 u 
= 39 u
= 39 x 6
= $234

Answer(s): $234
