There are two cell phone plans available from Cell Phones R Us company. Plan A charges $30 a month plus $0.01 for every text message. Plan B charges $20 a month plus $0.05 for every text message. How many text messages do you need to send in order for Plan A to cost the same as Plan B?

30 + 5m = 20 + m

20 + 5m = 30 + m

30 + 0.05m = 20 + 0.01m

20 + 0.05m = 30 + 0.01m
