Equilibrium Price: Skateboards The demand for your factory-made skateboards, in weekly sales, is
q = −4p + 50
if the selling price is $p. If you are selling them at that price, you can obtain
q = 3p − 30
per week from the factory. At what price should you sell your skateboards so that there is neither a shortage nor a surplus? (Round your answer to the nearest cent.)
