1. If the demand function is Qd = 190-5P and the supply function is Qs = -50+15P, calculate the figures for quantity demanded and quantity supplied for prices from \$1 to \$20.
2. Use these figures to plot the supply and demand curves. What is the equilibrium price and quantity?
3. The world price is \$6, plot this on your supply and demand diagram.
