Zane, Luis, Harry and Sean went shopping with a total of $748. After shopping, they had a total of $97 left. Luis spent $60. The amount Harry spent was ²₃ the amount spent by Zane. The total amount spent by Zane and Luis was $381 less than the total amount spent by Harry and Sean. How much did Zane and Sean spend altogether?

	Zane	Luis	Harry	Sean	Total
Before					$748
Change	- 3 u	- $60	- 2 u	- ?	- $651
After					$97

Total amount that Zane, Luis, Harry and Sean spent
= 748 - 97
= $651

Total amount that Zane and Luis spent
= 3 u + 60

Total amount that Harry and Sean spent
= 3 u + 60 + 381
= 3 u + 441 

Total amount that Zane, Luis, Harry and Sean spent
= 3 u + 60 + 3 u + 441
= 6 u + 501 

6 u + 501 = 651
6 u = 651 - 501
6 u = 150 

1 u = 150 ÷ 6 = 25

Total amount that Luis and Harry spent
= 2 u + 60
= 2 x 25 + 60
= 50 + 60
= $110

Total amount that Zane and Sean spent
= 651 - 110
= $541

Answer(s): $541
