Answer: you have 118 text messages.
Step-by-step explanation:
Let x represent the number of text messages that you have or sent.
A cell phone company charges a monthly fee plus $.25 for each text message. The monthly fee is $30. This means that the total cost of x sending x messages in a month would be
0.25x + 30
If you owe $59.50, then your total cost is $59.50
Therefore,
59.50 = 0.25x + 30
0.25x = 59.50 - 30
0.25x = 29.5
x = 29.5/0.25
x = 118
