3. (challenging) Suppose gold buyers are located in New York and Zurich. At the current price of gold, $400 an ounce, total quantity demanded (QNY + Qzurich) for gold is 10,000 ounces; and the price elasticity of demand for gold in New York and Zurich are 3 and 2 respectively. The slope of each demand curve and current price of gold in New York is the same as in Zurich.
