Consumer and Producer Surplus Given a demand function p $=$ f$($q$)$ and a supply function p $=$ g$($q$),$ and the equilibrium point $($q$*,$ p$*)$ The consumer surplus $=$ The producer surplus $=$ The sum of the consumer surplus and producer surplus is the total gains from trade. What are the units of consumer and producer surplus? The units are $($price units$)($quantity units$)=$ money! Example:The demand and supply functions for a certain product are given by p$=150-\mathrm{.}5$q and p$=\mathrm{.}002$q$^2+1\mathrm{.}5.$ where p is in dollars and q is the number of items. a$.$ Find the equilibrium point. b$.$ Find the consumer surplus at the equilibrium price. c$.$ Find the producer surplus at the equilibrium price.
