ISSUES IN SOLUTION

Some students will set up their axes differently. For this problem, that should cause no additional trouble. This is nice, since students can take pride in successfully completing the problem in a way that is likely to be different from their neighbors. To further this, some students might simplify the problem a bit by working in units of 100 feet.

The algebra involved in successfully minimizing the functions in this problem is quite involved if done by hand.
