Answer: 1 U.S. dollar equals 1.44 Swiss francs
Explanation:
The Purchasing power parity (PPP) is used by economists or financial analysts to make comparison between the standards of living and the economic productivity that exist between countries.
From the question, we are told that a box of chocolate candy costs 28.80 Swiss francs in Switzerland and $20 in the United States. The current exchange rate will be:
1 U.S dollar = (28.80/20) Swiss Francs
1 U. S Dollar = 1.44 Swiss Francs
