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 using x as the variable and then solve the equation.

Answer 1

Ok if he paid.

59.50-30.00=29.50

so he paid 29.50 dollars more 

29.50/0.25=118

so he texted 118 times

Answer 2

.25x + 30 = 59.50 is the equation.

now subtract 30 from each side leaving you with:

.25x = 29.50

now divide by .25 on each side.

x = 118
      
You sent 118 text messages.
