Suppose a demand function is given as Pd=2411.1Q where Pd is the price in dollars and Q is the quantity available for trade. At the same time, a supply function is given as PS=21 +4.1Q. Assume that the government mandates a price cap (maximum price) of $34.29, what would be the excess quantity supplied? [Use positive values to represent a surplus, negative for a shortage and 0 for a balanced supply and demand. For example -10 would imply a shortage while 5 would imply a surplus.]
