45 + 0.25m = 60.50
0.25m = 60.50 - 45
0.25m = 15.5
m = 15.5/0.25
m = 62 <== there were 62 text messages (m)

Answer:

62 text messages.

Step-by-step explanation:

Let x represent number of text messages.

We have been given that Dante's cell phone company charges $45 per month for unlimited calls and internet use and $0.25 per text message.

The total cost of Dante's bill would be [tex]0.25x+45[/tex]  

We have been given that last month Dante's bill was $60.50. We can represent this information in an equation as:

[tex]0.25x+45=60.50[/tex]

[tex]0.25x+45-45=60.50-45[/tex]

[tex]0.25x=15.5[/tex]

[tex]\frac{0.25x}{0.25}=\frac{15.5}{0.25}[/tex]

[tex]x=62[/tex]

Therefore, Dante sent 62 text messages last month.
