Suppose that the nominal exchange rate is 80 yen per dollar, that the price of a basket of goods in the U. S. is $500 and the price of a basket of goods in Japan is 50,000 yen. Suppose that these values change to 100 yen per dollar, $600, and 70,000 yenThen the real exchange rate would: a. appreciate which by itself would make U. S. net exports fall.
b. appreciate which by itself would make U. S. net exports rise.
c. depreciate which by itself would make U. S. net exports fall.
c. depreciate which by itself would make U. S. net exports rise

a. appreciate which by itself would make U.S. net exports fall.

Explanation:

Nominal exchange rate 80 yen per $, cost of basket of goods in Japan is 50,000 yen = $625, while the same basket of goods costs $500 in the US. The relationship between Japan and the US is $500:$625 or 4:5 or 0.80.

If the nominal exchange rate increases to 100 yen per $, and the cost of the basket of goods is 70,000 yen = $700, while the same basket of goods costs $600 in the US. The relationship between Japan and the US is $600:$700 or 6:7 = 0.86.

Since the real exchange rate appreciated, US exports will become more expensive.
