I need assistance with the last three problems. I don't think the questions are hard just don't have time.

1. Why might some prefer a prix fixe (fixed price) dinner costing about the same as an la carte one (where you pay individually for each item)? (Assume the food is identical.) 2. Consider a person with the following utility function over wealth: u(w) = ew, where e is the exponential function (approximately equal to 2.7183) and w = wealth in hundreds of thousands of dollars. Suppose that this person has a 40% chance of wealth of $100,000 and a 60% chance of wealth of $2,000,000 as summarized by P(0.40, $100,000, $2,000,000). a. What is the expected value of wealth? b. Construct a graph of this utility function (recall your excel?). c. Is this person risk averse, risk neutral, or a risk seeker? d. What is this person's certainty equivalent for the prospect? 3. Consider two prospects. Problem 1: Choose between Prospect A: Prospect B: $2,500 with probability 0.33 $2,400 with probability 0.66 Zero with probability 0.01 $2,400 with probability 1.00 Problem 2: Choose between Prospect C: Prospect D: $2,500 with probability 0.33 Zero with probability 0.67 $2,400 with probability 0.34 Zero with probability 0.66 It has been shown by Daniel Kahneman and Amos Tversky (1979, \"Prospect theory: An analysis of decision under risk,\" Econometrica 47(2), 263-291) that more people choose B when presented with problem 1 and when presented with problem 2, most people choose C. These choices violate expected utility theory. Why
