Information for questions 1-5 The graph below shows the supply and demand for coffee in a certain country. The world price of coffee is $1.00 per pound. This is a small country, therefore whatever it does will not affect this world price. The government of this country charges a tariff of $0.80 per pound of imported coffee. Except where noted, all questions refer to the country’s situation after the tariff has been levied by the government. For all questions, enter a whole or decimal number, as appropriate.
