Anita has 180 minutes to prepare mailers for her job. It takes her at least 15 minutes to set up materials and 3 minutes per mailer to prepare them. If m represents the number of mailers she prepares, then 3m + 15 ≤ 180 represents the number she can finish. What is the greatest number of mailers Anita can prepare in the time she has?
