Question

A cell phone company charges a monthly fee plus $0.25 for each text message. The monthly fee is $30.00 and you owe $59.50. How many text messages did you have? Write an equation to represent the situation

Answer 1

The equation would be .25x + 30= 59.50
The reason for this is that you know you will always have 30$ but the .25 depends on how many texts so it needs the x. It is set equal to 59.50 because that is the total.
