Florida Orange Juice is a product of Florida's Orange Growers' Association. Demand and supply of the product are both highly sensitive to changes in the weather. During hot summer months, demand for orange juice and other beverages grows rapidly. On the other hand, hot dry weather has an adverse effect on supply by reducing the size of the orange crop. Demand and supply functions for Florida orange juice are as follows: QD = 4,500 1,600P + 2,000PS + 100T (Demand) QS = 6,000 + 2,400P 500PL 120T (Supply) where P is the average price of Florida ($ per case), PS is the average retail price of canned soda ($ per case), T is the average daily high temperature (degrees), PL is the average price of unskilled labour ($ per hour).

A. When quantity is expressed as a function of price, what are the Florida demand and supply curves if P = $11, PS = $5, T = 75 degrees, PL = $6.

B. Calculate the surplus or shortage of Florida orange juice when P = $5, $10, and $15.

C. Calculate the market equilibrium price-output combination
