Zane, Dylan, Albert and Flynn went shopping with a total of $679. After shopping, they had a total of $26 left. Dylan spent $50. The amount Albert spent was ⁵₇ the amount spent by Zane. The total amount spent by Zane and Dylan was $273 less than the total amount spent by Albert and Flynn. How much did Zane and Flynn spend altogether?

	Zane	Dylan	Albert	Flynn	Total
Before					$679
Change	- 7 u	- $50	- 5 u	- ?	- $653
After					$26

Total amount that Zane, Dylan, Albert and Flynn spent
= 679 - 26
= $653

Total amount that Zane and Dylan spent
= 7 u + 50

Total amount that Albert and Flynn spent
= 7 u + 50 + 273
= 7 u + 323 

Total amount that Zane, Dylan, Albert and Flynn spent
= 7 u + 50 + 7 u + 323
= 14 u + 373 

14 u + 373 = 653
14 u = 653 - 373
14 u = 280 

1 u = 280 ÷ 14 = 20

Total amount that Dylan and Albert spent
= 5 u + 50
= 5 x 20 + 50
= 100 + 50
= $150

Total amount that Zane and Flynn spent
= 653 - 150
= $503

Answer(s): $503
