Answer:
<em>f</em> has no critical points.
Step-by-step explanation:
We are given:

A function has critical points whenever its derivative equals 0 or is undefined.
Differentiate the function:

Since this will never be undefined, solve for its zeros:

Hence:

Recall that the value of sine is always between -1 and 1.
Thus, no real solutions exist.
Therefore, <em>f</em> has no critical points.
$20 - $12.75 = $7.25
$7.25 / $0.75 = 9.6
So you can buy C) 9.6 cookies.
