Suppose your company imports computer motherboards from Singapore. The exchange rate is 1.4164 Singapore dollars per U.S. dollar. You have just placed an order for 40,000 motherboards at a cost to you of 209.95 Singapore dollars each. You will pay for the shipment when it arrives in 90 days. You will sell the motherboards for $209.99 each. Calculate your profit if (a) the exchange rate does not change, (b) the exchange rate goes up and down by 12% over the next 90 days. What is the break-even exchange rate in American terms rounded to 4 decimal places?
