5 pounds = 20 potatoes
400 pounds = x
(cross-multiply above and you'll get 400 pounds = 1600 potatoes )
divide that by 2, and you'll get 800 (because 2 potatoes per fries)
1 = $0.95 (1 because i divided 1600 by 2, if in hadn't it would be 2)
800 = x
(you cross multiply again), and you'll get $760
Hope it helped!
