Eric, Lee, John and Brandon went shopping with a total of $598. After shopping, they had a total of $112 left. Lee spent $80. The amount John spent was ²₅ the amount spent by Eric. The total amount spent by Eric and Lee was $36 less than the total amount spent by John and Brandon. How much did Eric and Brandon spend altogether?

	Eric	Lee	John	Brandon	Total
Before					$598
Change	- 5 u	- $80	- 2 u	- ?	- $486
After					$112

Total amount that Eric, Lee, John and Brandon spent
= 598 - 112
= $486

Total amount that Eric and Lee spent
= 5 u + 80

Total amount that John and Brandon spent
= 5 u + 80 + 36
= 5 u + 116 

Total amount that Eric, Lee, John and Brandon spent
= 5 u + 80 + 5 u + 116
= 10 u + 196 

10 u + 196 = 486
10 u = 486 - 196
10 u = 290 

1 u = 290 ÷ 10 = 29

Total amount that Lee and John spent
= 2 u + 80
= 2 x 29 + 80
= 58 + 80
= $138

Total amount that Eric and Brandon spent
= 486 - 138
= $348

Answer(s): $348
