Use a steamship to tow several small boats loaded with equal amounts of cargo back and forth between two ports. It is known that if each time 4 small boats are towed, 16 round trips can be made in a day; if each time 7 small boats are towed, 10 round trips can be made in a day. The daily number of round trips is a linear function of the number of small boats towed (the number of small boats towed per trip remains the same throughout the day). How many round trips per day and how many small boats per trip should be towed to maximize the cargo volume?
