1. Martinis and expenditure function (25 points). Mr. A is very particular about his martinis, he only enjoys them made in the exact proportion of two parts gin (g) to one part vermouth (v). Hence, we can rewrite Mr. A's utility function as U = min(g/2, v) a. Graph Mr. A's indifference curve in terms of g and v for various levels of utility. Show that, regardless of the prices of the two ingredients, Mr. A will never alter the way he mixes martinis. b. Calculate the demand functions for g and v. c. Using the results from part (b), what is Mr. As indirect utility function? d. Calculate Mr. A's expenditure function
