dantes cell phone company charges $45 per month for unlimited calls and internet use and $0.25 per text message. his last cell phone bill was $60.50. how many text messages did dante send the last month?

Answer 1

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 2

62 text messages.

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
`0.25x+45`

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

`0.25x+45=60.50`

`0.25x+45-45=60.50-45`

`0.25x=15.5`

`(0.25x)/(0.25)=(15.5)/(0.25)`

`x=62`

Therefore, Dante sent 62 text messages last month.
