Question

Suppose that the supply and demand of wheat depend on the price of wheat (p), the amount of annual rainfall (r), and the level of disposable consumer income (). The equations describing the supply and demand curves are given by: Qs-20r+100p Qd-4000-100p 101 (a) Using the supply and demand equations for wheat, solve for the equilibrium price as a function of I and r. " (b) Using the supply and demand equations for wheat, solve for the equilibrium quantity as a function of I and r.e (c) Using the supply and demand equations for wheat above, determine how the equilibrium price and quantity vary with an increase in rainfallr) holding other factors that influence supply and demand fixed. d) Using the supply and demand equations for wheat above, with an increase in income(). explain in words how equilibrium quantity changes
