Assume the United States has the following import$/$export volumes and prices. It undertakes a major "devaluation" of the dollar, say $18\%$ on average against all major trading partner currencies$-$ hence the dollar goes from a value of $2$ $$/$fc to a value of $2\mathrm{.}4390$ $$/$fc$.$

Initial spot exchange rate, $$/$fc $2\mathrm{.}00$

Price of exports, dollars $($$$)20\mathrm{.}0000$

Price of imports, foreign currency $($fc$)12\mathrm{.}0000$

Quantity of exports, units $100$

Quantity of imports, units $120$

Percentage devaluation of the dollar $18\mathrm{.}00$

What is the pre$-$devaluation trade balance?

What is the post$-$devaluation trade balance?
