Answer to Question 1

C

Answer to Question 2

In this case, to arrive at the optimal choice, optimization in differences will be arithmetically easier to implement than optimization in levels. If she optimizes in levels, she would evaluate the total net benefit of a four-day trip and compare it to the total net benefit of a five-day trip. On the other hand, optimization in differences will only require an estimation of the net benefit of the fifth day, as the first four days are common in both options. This makes it easier and faster to implement.
