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.
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
.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.
