There are 12 farm vehicles and 6 farm vehicles in warehouse A and B respectively. Now 10 farm vehicles need to be transferred to county a and 8 farm vehicles need to be transferred to county B. It is known that the freight of transporting one farm vehicle from warehouse A to county a and county B is 40 yuan and 80 yuan respectively; the freight of transporting one farm vehicle from warehouse B to county a and county B is 30 yuan and 50 yuan respectively. (1) suppose x farm vehicles are transferred from warehouse B to county a, find the function of total freight y with respect to X (2) if the total freight is required to be no more than 900 yuan, how many kinds of transportation schemes are available; (3) how much is the minimum freight for the lowest transportation scheme?
(1) If warehouse B transfers x agricultural vehicles (x ≤ 6) to county a, warehouse B transfers 6-x agricultural vehicles to county B, and county a needs 10 vehicles. Therefore, a transfers 10-x agricultural vehicles to county a, and county a transfers x + 2 agricultural vehicles to county B. according to the freight of each transfer mode, the equation can be listed as follows: y = 40 (10-x) + 80 (x + 2) + 30x + 50 (
