_{Suppose your company imports computer motherboards from Singapore. The exchange rate is currently 1.5124 S$/US$. You have just placed an order for 25,000 motherboards at a cost to you of 231.45 Singapore dollars each. You will pay for the shipment when it arrives in 90 days. You can sell the motherboards for $164 each. What is the break-even exchange rate? What percentage decrease does this represent in terms of the Singapore dollar versus the U.S. dollar?}
