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?
