Homework Statement

The Attempt at a Solution
Looking for some guidance for this problem, I will add information as i go along.
I think the steps are:
1) Develop a formula that represents the cost
2) Find critical points
3) evauluate the critical points
What i am unsure of is am i allowed to vary the length of the highway and gravel road? I am asked to maximize profit or i can minimize cost. Is this cost of operating or of construction as well? If its of operating only i can easily deduct the construction cost from the inital 7.8 million. Also if its of operating only, can i not say operate as fast as possible to reduce hours?
Please advise
thank you.
