Suppose the demand and supply curves for wheat in a country are as follows, where p is $ per ton and Q is thousands of tons per year:

QD= 500 - pQS= 100 + 0.6p

• Calculate the market equilibrium price: $
• Calculate the value of consumer surplus at the equilibrium: $(thousands)
• Calculate the deadweight loss associated with an $80 per ton tax on wheat:$(thousands)
