Neco 2019 Government Question 3

In 2019 Nigeria signed a trade agreement that (i) reduced the tariff on imported machinery from \(15\\%\) to a rate that is 40\\% lower, and (ii) introduced an export subsidy on cocoa equal to \(25\\%\) of the export value. Before the agreement, Nigeria imported machinery worth \$200\,\text{million} and exported cocoa worth \$120\,\text{million}. After the agreement, the quantity of machinery imported fell by \(10\\%\) and the quantity of cocoa exported rose by \(20\\%\), while the tariff and subsidy rates applied to the new quantities. Calculate the net change in government revenue (in millions of dollars) resulting from the tariff loss and the subsidy outlay. Give your answer to one decimal place; a negative answer indicates a loss.
