Cody, Flynn, Eric and Ken went shopping with a total of $558. After shopping, they had a total of $75 left. Flynn spent $80. The amount Eric spent was ³₅ the amount spent by Cody. The total amount spent by Cody and Flynn was $203 less than the total amount spent by Eric and Ken. How much did Cody and Ken spend altogether?

	Cody	Flynn	Eric	Ken	Total
Before					$558
Change	- 5 u	- $80	- 3 u	- ?	- $483
After					$75

Total amount that Cody, Flynn, Eric and Ken spent
= 558 - 75
= $483

Total amount that Cody and Flynn spent
= 5 u + 80

Total amount that Eric and Ken spent
= 5 u + 80 + 203
= 5 u + 283 

Total amount that Cody, Flynn, Eric and Ken spent
= 5 u + 80 + 5 u + 283
= 10 u + 363 

10 u + 363 = 483
10 u = 483 - 363
10 u = 120 

1 u = 120 ÷ 10 = 12

Total amount that Flynn and Eric spent
= 3 u + 80
= 3 x 12 + 80
= 36 + 80
= $116

Total amount that Cody and Ken spent
= 483 - 116
= $367

Answer(s): $367
