4. Claudia lives in Cambridge, and allocates her monthly income of $500 between DVDs and shoes. The price of each DVD is $10 and the price of each pair of shoes is $50. a) Draw Claudia's budget constraint on a well-labeled graph, with DVDs on the horizontal axis. b) Assume that Claudia considers one pair of shoes to be perfect substitute to one DVD.
