Question

the strength of the u.s. dollar relative to other currencies depends mainly on select one: a. how much gold backs the money supply. b. the performance of the u.s. economy relative to other economies. c. the rate of inflation in the united states. d. exchange rate decisions made by the international monetary fund.

Explanation:

The value of a currency like the U.S. dollar in the foreign - exchange market is largely determined by the economic performance of the country relative to others. A stronger U.S. economy compared to others attracts foreign investment, increasing the demand for the dollar and strengthening it. Gold no longer backs the money supply in the modern U.S. monetary system. While inflation affects the dollar's value, it is part of the broader economic performance. The International Monetary Fund does not directly make exchange - rate decisions for the U.S. dollar.

Answer:

B. the performance of the U.S. economy relative to other economies.
