1. Jimmy Joe Bob, the self-processed truck king of Dog Patch Arkansas, sells used trucks (which he spells "trux"). The normal demand curve for Jimmy's trucks is: QD = 100 -0.03P+ 0.0045PB-0.6PG +0.0051 +.012A Where Q-D is quantity demanded, P is the price of JJB's trucks, PB is the price of Bubba Will's - Jimmy's only competitor – trucks, PG is the price of gas, I is income, and A is JJB's advertising expenditures. A) If Jimmy sets his price at $4000, Bubba sets his price at $3000, the price of gas is $3.00 per gallon, average income in the community is $2500 and Jimmy spends $500 on advertising how many trucks does Jimmy sell? B) Derive the inverse demand curve for Jimmy's trucks. C) If the marginal cost of selling a truck is $2800 how many trucks should Jimmy sell to maximize his profits, and at what price should he sell those trucks? D) At that price and quantity what are Jimmy's profits?
