Fabian, Lee, Ryan and Billy went shopping with a total of $760. After shopping, they had a total of $95 left. Lee spent $40. The amount Ryan spent was ⁵₆ the amount spent by Fabian. The total amount spent by Fabian and Lee was $237 less than the total amount spent by Ryan and Billy. How much did Fabian and Billy spend altogether?

	Fabian	Lee	Ryan	Billy	Total
Before					$760
Change	- 6 u	- $40	- 5 u	- ?	- $665
After					$95

Total amount that Fabian, Lee, Ryan and Billy spent
= 760 - 95
= $665

Total amount that Fabian and Lee spent
= 6 u + 40

Total amount that Ryan and Billy spent
= 6 u + 40 + 237
= 6 u + 277 

Total amount that Fabian, Lee, Ryan and Billy spent
= 6 u + 40 + 6 u + 277
= 12 u + 317 

12 u + 317 = 665
12 u = 665 - 317
12 u = 348 

1 u = 348 ÷ 12 = 29

Total amount that Lee and Ryan spent
= 5 u + 40
= 5 x 29 + 40
= 145 + 40
= $185

Total amount that Fabian and Billy spent
= 665 - 185
= $480

Answer(s): $480
