Producers' Surplus The demand function for a certain brand of CD
is given by p = −0.01x2 − 0.2x + 9 where p is the unit price in
dollars and x is the quantity demanded each week, measured in units
of a thousand. The supply function is given by p = 0.01x2 + 0.3x +
2 where p is the unit price in dollars and x stands for the
quantity that will be made available in the market by the supplier,
measured in units of a thousand. Determine the producers' surplus
if the market price is set at the equilibrium price. (Round your
answer to the nearest dollar.)
