Hi can someone help me with this question. This is on my review. Thanks!

The monthly cost C, in dollars, for

international calls on a certain cellular phone plan is

modeled by the function where x is the

number of minutes used.

(a) What is the cost if you talk on the phone for x=43

minutes?

(b) Suppose that your monthly bill is $44.10. How many

minutes did you use the phone?

(c) Suppose that you budget yourself $80 per month for the

phone. What is the maximum number of minutes that

you can talk?
