Suppose the domestic market demand function in a certain market where Q is measured in thousands of units is Q = 20 - 2.5P, and the domestic market supply function is QS = 2.5P - 7.5. Suppose further that the world price for the good in question is $3.40 per unit. If the government places a $1.20 tariff on imported units of this good, how much revenue does the tariff generate? $3,600 $5,400 $3,000 $3,200
