Lumyn Electronics is now using social networking to expand their reputation and reach new potential customers. The company has found that the number N of new potential customers in their 12,000 people community that have heard of their company can be modeled by the equation

N = 12,000(1 - e^-0.0008t)

where t is the number of days elapsed since starting using social networking. How long will it take for 100 new potential customers to have heard of the company?
