Please on your graphs, please label axes, curves, intercepts, slopes, and all points relevant to the question.

1. (25) Paul has preferences over balls (B) and skateboards (S). A ball has a price, PR = 10. A skateboard has a price, Ps = 20. Consider that Paul receives 5 balls and 5 skateboards for his birthday (along with gift receipts so that he may return items for their purchase price). (a) (5) Plot and label Paul's endowment (the bundle he starts off with) in the space of B and S. Put B on the horizontal axis. (b) (5) Calculate the intercepts of the budget line. Use these points, along with the endowment from (a), to draw Paul's budget line. Use a separate graph from (a). (c) (7.5) Now consider that there is a 25% restocking fee for returned skateboards. Draw Paul's budget line. Use a separate graph. (d) (7.5) Ignore the restocking fee described in (c). Now consider that there is a promotion. Specifically, balls are 50% off. Draw Paul's budget line under this promotion. Use a separate graph
