Chapter 6.2, Problem 85E
The following tables give price–demand and price–supply data for the sale of soybeans at a grain market, where x is the number of bushels of soybeans (in thousands of bushels) and p is the price per bushel (in dollars):
Tables for 85–86
Use quadratic regression to model the price–demand data and linear regression to model the price–supply data.
- (A) Find the equilibrium quantity (to three decimal places) and equilibrium price (to the nearest cent).
- (B) Use a numerical
integration routine to find the consumers' surplus and producers' surplus at the equilibrium price level.
