Owen, Jack, Lee and Sean went shopping with a total of $612. After shopping, they had a total of $169 left. Jack spent $80. The amount Lee spent was ³₄ the amount spent by Owen. The total amount spent by Owen and Jack was $99 less than the total amount spent by Lee and Sean. How much did Owen and Sean spend altogether?

	Owen	Jack	Lee	Sean	Total
Before					$612
Change	- 4 u	- $80	- 3 u	- ?	- $443
After					$169

Total amount that Owen, Jack, Lee and Sean spent
= 612 - 169
= $443

Total amount that Owen and Jack spent
= 4 u + 80

Total amount that Lee and Sean spent
= 4 u + 80 + 99
= 4 u + 179 

Total amount that Owen, Jack, Lee and Sean spent
= 4 u + 80 + 4 u + 179
= 8 u + 259 

8 u + 259 = 443
8 u = 443 - 259
8 u = 184 

1 u = 184 ÷ 8 = 23

Total amount that Jack and Lee spent
= 3 u + 80
= 3 x 23 + 80
= 69 + 80
= $149

Total amount that Owen and Sean spent
= 443 - 149
= $294

Answer(s): $294
