Always well dressed, Jim believes that "the shirt should match the tie." Thus, every time he buys a new shirt (good x) he buys one perfectly matching tie (good y). What is Jim's utility function? Budget line 1: Jim's budget for shirts and ties is $850. Shirts cost $40 each. Ties cost $30 each. Draw a graph with budget line one. Draw an indifference curve. Identify Jim's point of optimization. (If you want to avoid the risk of errors, use Gauss.) Include all necessary numbers. Budget line 2: Budget = $1,000. Shirts cost $50 each. Ties cost $50 each. Draw budget line 2 and one indifference curve to optimize Jim's choice. Is Jim better off on budget line 1 or on budget line 2? Explain.
