Suppose the current exchange rate is 115 yen per dollar. We currently have a demand for 50 units of our product when the unit price is 800 yen. The cost of producing and shipping the product to Japan is $6, and the current elasticity of demand is –2.5. Find the optimal price to charge for the product (in yen) for each of the following exchange rates: 60 yen/$, 80 yen/$, 100 yen/$, 120 yen/$, 140 yen/$, and 160 yen/$. Assume the demand function is linear.
