Market Forces

It's Saturday at Oakfield market. Set the price at the apple stall, the pizza van and the honey stall. The queue shows the quantity demanded and the crates show the quantity supplied: too low a price leaves buyers with nothing (excess demand), too high a price leaves stock unsold (excess supply). Use market forces to clear each market at its equilibrium price, then drag the demand and supply curves when the news breaks and find the new equilibrium.
