In May $1991,$ Car and Driver described a Jaguar that sold for $$980,000.$ At that price only $50$ have been sold. It is estimated that $350$ could have been sold if the price had been $$560,000.$ Assuming that the demand curve is a straight line, and that $$560,000$ and $350$ are the equilibrium price and quantity, find the consumer surplus at the equilibrium price. Consumer surplus $=\_\_\_\_\_$ dollars.
