In theory you wear each set of trays for 2 weeks. But, that is assuming you wear them often enough. You are only supposed to take them out to eat. It also depends on how your teeth respond to them.
Also, in my case, I have 8 trays for the upper teeth and 15 trays for the lower teeth. My upper teeth are not as out of line - most of the alignment is needed on the lower teeth. So, I'll be wearing them on the lower teeth longer than the upper.
