Thread: Supply and Demand

The supply and demand for crabmeat in a local fish store are related by the equations:
Demand p=D(q)=19-2q and
Supply p= S(q)=6q+3

When p represents the price in dollars per pound and q represents the quantity of crabmeat in pounds per day.
a.) Find the quantity supplied and demanded at each of the following prices: $10, $15, $18.
b.) Find the equilibrium point.

Hey JP2012.

Hint: You have values for p so just solve for q with these values.
