Ethan, Tommy, Rael and Andy went shopping with a total of $649. After shopping, they had a total of $126 left. Tommy spent $40. The amount Rael spent was ⁵₆ the amount spent by Ethan. The total amount spent by Ethan and Tommy was $299 less than the total amount spent by Rael and Andy. How much did Ethan and Andy spend altogether?

	Ethan	Tommy	Rael	Andy	Total
Before					$649
Change	- 6 u	- $40	- 5 u	- ?	- $523
After					$126

Total amount that Ethan, Tommy, Rael and Andy spent
= 649 - 126
= $523

Total amount that Ethan and Tommy spent
= 6 u + 40

Total amount that Rael and Andy spent
= 6 u + 40 + 299
= 6 u + 339 

Total amount that Ethan, Tommy, Rael and Andy spent
= 6 u + 40 + 6 u + 339
= 12 u + 379 

12 u + 379 = 523
12 u = 523 - 379
12 u = 144 

1 u = 144 ÷ 12 = 12

Total amount that Tommy and Rael spent
= 5 u + 40
= 5 x 12 + 40
= 60 + 40
= $100

Total amount that Ethan and Andy spent
= 523 - 100
= $423

Answer(s): $423
