Step 1. Draw a demand and supply model to illustrate the market for salmon in the year before the good weather conditions began.
The demand curve D0 and the supply curve S0 show that the original equilibrium price is $3.25 per pound and the original equilibrium quantity is 250,000 fish. (This price per pound is what commercial buyers pay at the fishing docks. What consumers pay at the grocery is higher.)
Step 2. How did the economic event affect supply or demand?
Would you expect rain and good weather to affect the supply of salmon or the demand?
