Brandon, Pierre, Julian and Andy went shopping with a total of $602. After shopping, they had a total of $87 left. Pierre spent $80. The amount Julian spent was ⁴₅ the amount spent by Brandon. The total amount spent by Brandon and Pierre was $85 less than the total amount spent by Julian and Andy. How much did Brandon and Andy spend altogether?

	Brandon	Pierre	Julian	Andy	Total
Before					$602
Change	- 5 u	- $80	- 4 u	- ?	- $515
After					$87

Total amount that Brandon, Pierre, Julian and Andy spent
= 602 - 87
= $515

Total amount that Brandon and Pierre spent
= 5 u + 80

Total amount that Julian and Andy spent
= 5 u + 80 + 85
= 5 u + 165 

Total amount that Brandon, Pierre, Julian and Andy spent
= 5 u + 80 + 5 u + 165
= 10 u + 245 

10 u + 245 = 515
10 u = 515 - 245
10 u = 270 

1 u = 270 ÷ 10 = 27

Total amount that Pierre and Julian spent
= 4 u + 80
= 4 x 27 + 80
= 108 + 80
= $188

Total amount that Brandon and Andy spent
= 515 - 188
= $327

Answer(s): $327
