Suppose that both gold and silver are used as international means of payment and the exchange rates among currencies are determined by either their gold or silver contents. Suppose that the dollar was pegged to gold at $20 per ounce, the Japanese yen is pegged to gold at 120,000 yen per ounce and to silver at 8,000 yen per ounce of silver, and the Australian dollar is pegged to silver at $5 per ounce of silver. What would the exchange rate between the U.S. dollar and Australian dollar be under this system?

First, we need to determine the exchange rates between gold and silver as follows:

1 ounce of gold = 120,000 yen (Japanese yen)
1 ounce of silver = 8,000 yen (Japanese yen)
1 ounce of silver = $5 (Australian dollar)

Therefore, 1 ounce of gold = (120,000 yen / 8,000 yen) x $5 = $75 (Australian dollar)

Since the U.S. dollar is pegged to gold at $20 per ounce and the Australian dollar is pegged to silver at $5 per ounce, we can calculate the exchange rate between the U.S. dollar and Australian dollar as follows:

1 ounce of gold = $20 (U.S. dollar)
1 ounce of gold = $75 (Australian dollar)

Thus, $1 U.S. = ($75 / $20) Australian = $3.75 Australian.

Therefore, the closest answer is C) $1 U.S. = $3 Australian, with a slight adjustment due to rounding, making the correct answer C) $1 U.S. = $3 Australian.
