Question

Tommy currently has a cell phone plane for text messaging with Phone-Phriends which charges $0.20 per text message. Tommy is considering switching to
an unlimited plan which costs $49 per month. How many messages each month must Tommy send for it to be cost effective to switch to the unlimited
plan?

Answer 1

Answer:

49÷0.20= 245

He has to be able to have a number of text each month to be able to switch so 0.20 for each text he sends each month so you have to divide from 49.
