A new health club has just opened. Statistics suggest that the fraction of clients who will still be attending the club t months after their initial visit is given by f(t)=e−0.08tf ( t ) = e ^ { - 0.08 t } . The club initially accepts 1,000 people for membership and plans to accept new members at the rate of 50 per month. Approximately 680 people will be in the club 2 years from now.
