Tommy, Ivan, Warren and Ben went shopping with a total of $805. After shopping, they had a total of $103 left. Ivan spent $80. The amount Warren spent was ⁵₈ the amount spent by Tommy. The total amount spent by Tommy and Ivan was $62 less than the total amount spent by Warren and Ben. How much did Tommy and Ben spend altogether?

	Tommy	Ivan	Warren	Ben	Total
Before					$805
Change	- 8 u	- $80	- 5 u	- ?	- $702
After					$103

Total amount that Tommy, Ivan, Warren and Ben spent
= 805 - 103
= $702

Total amount that Tommy and Ivan spent
= 8 u + 80

Total amount that Warren and Ben spent
= 8 u + 80 + 62
= 8 u + 142 

Total amount that Tommy, Ivan, Warren and Ben spent
= 8 u + 80 + 8 u + 142
= 16 u + 222 

16 u + 222 = 702
16 u = 702 - 222
16 u = 480 

1 u = 480 ÷ 16 = 30

Total amount that Ivan and Warren spent
= 5 u + 80
= 5 x 30 + 80
= 150 + 80
= $230

Total amount that Tommy and Ben spent
= 702 - 230
= $472

Answer(s): $472
