1. Consider a local department store which only sells jeans (J) and sweaters (S). Jeans cost $20 and sweaters cost $30. For each of the examples below, graph the budget constraint our consumer faces, putting J on the horizontal axis and S on the vertical one. Be sure to label our consumer's initial bundle (what he comes into the store with). (a) The consumer comes into the store with 20 sweaters to exchange (and a gift receipt!). (b) The consumer comes into the store with 20 sweaters to exchange (and a gift receipt!). There is a 50% restocking fee. (c) The consumer comes into the store with 10 jeans and 10 sweaters to exchange (and a gift receipt!). There is a 50% restocking fee on jeans only.
