We know that a café charges $0.10 per minute to use the internet.
That means that the total charges will increase $0.1 per minute.
So, now we can make a table that models the situation
Number of minutes Total charges
1 $0.10
2 $0.20
3 $0.30
4 $0.40
Another way to make the table is modeling a function.
In this case the function is
Where y is the total charges and x is the number of minutes.
We can verify each value of the table with the function and we will see that it is correct.
Finally, the answer is the first option.
