I am not sure.
The Attempt at a Solution
I really don't understand how to go about this. I really need someone to help walk me through this where I can ask questions along the way. It is not so much that I don't understand what to do, I just don't understand how to do it. How to apply the Calculus. If you want to use a different problem or change the numbers or whatever, I am fine with that. I am not looking to have my homework done for me, I really need to get a grasp on how to apply Calculus to these problems. In fact, I would prefer it that way if you have time, energy, or resources to make up a different problem that uses the same techniques. But if not, explaining this one to me will work. Because I do not even understand what part b is asking me...
