The demand curve for a good is given by the equation QD $=1000-5$ P$,$ and the

supply curve is given by the equation QS $=-500+10$P$,$ where P represents the

price of the good $($measured in dollars per unit$)$ and Q represents the quantity

of the good $($measured in units$).$ What is the consumer surplus? What is the

producer surplus? What is the total surplus? What is the deadweight loss?
