Flynn, Sam, Vincent and Ethan went shopping with a total of $867. After shopping, they had a total of $95 left. Sam spent $40. The amount Vincent spent was ⁴₇ the amount spent by Flynn. The total amount spent by Flynn and Sam was $482 less than the total amount spent by Vincent and Ethan. How much did Flynn and Ethan spend altogether?

	Flynn	Sam	Vincent	Ethan	Total
Before					$867
Change	- 7 u	- $40	- 4 u	- ?	- $772
After					$95

Total amount that Flynn, Sam, Vincent and Ethan spent
= 867 - 95
= $772

Total amount that Flynn and Sam spent
= 7 u + 40

Total amount that Vincent and Ethan spent
= 7 u + 40 + 482
= 7 u + 522 

Total amount that Flynn, Sam, Vincent and Ethan spent
= 7 u + 40 + 7 u + 522
= 14 u + 562 

14 u + 562 = 772
14 u = 772 - 562
14 u = 210 

1 u = 210 ÷ 14 = 15

Total amount that Sam and Vincent spent
= 4 u + 40
= 4 x 15 + 40
= 60 + 40
= $100

Total amount that Flynn and Ethan spent
= 772 - 100
= $672

Answer(s): $672
