Car rental agency A charges a cents for the first mile of ride and x cents for every further mile. Car rental agency B charges b cents for the first mile of ride and y cents for every further mile. Can the ratio of the total charges of A and B for a d mile ride be 0.86?
(1) a : b = 3 : 4 and x: y = 17 : 20
(2) a < b and x < y. Had the charge for the first mile of ride of each agency been 12 cents higher, the ratio of the total charges of A and B for a d mile ride would have been at most 9 : 10.
