how many classes a week should a gym that has 150 members offer?
In general, I would start with an early class (before work) often times 5:30 am daily. Then an afterwork class daily 5:30 or 6 pm. Other times are right after moms drop kids off at school. 9 am or so. From there once they fill up you can add classes next to them to take pressure off that specific time. Above answers are right on also. It all depends on what you are going for.
