Problema Solution
A newly established carpenter wishes to mail out letters adversting her services to the families of a small town. She has a choice of mailing the letters first class or obtaining a bulk-rate permit and mailing them at the cheaper bulk rate. The bulk-rate permit costs $190 and each piece of bulk mail then costs 28.1 cents. If the first-class rate is 45 cents, how many pieces would she have to mail in order to make bulk rate the cheaper way to go?

190 + 0.281x <= 0.45x
by solving we find:
x >= 1124.3
