1. Suppose the world is under the bimetallism currency system. Suppose that the dollar was pegged to gold at $30 per ounce, the French franc is pegged to gold at 70 francs per ounce and to silver at 5 francs per ounce of silver, and the German mark pegged to silver at 1 mark per ounce of silver. Under this exchange rate, 1 German mark is worth how much dollar? Round to the nearest cents.
