A student is deciding on two different cell phone companies. Allied Communications charges $50.00 a month plus 2¢ per minute used. Bussard Media charges $20.00 a month plus 5¢ per minute used. The "daily break-even" point is the number of minutes a customer would have to use each day in order for the two plans to cost the same. Assuming a 30-day month, what is the break-even point for these two plans?
