Suppose your company imports computer motherboards from Singapore. The exchange rate is currently 1.5123 S$/US$. You have just placed an order for 24,000 motherboards at a cost to you of 231.50 Singapore dollars each. You will pay for the shipment when it arrives in 90 days. You can sell the motherboards for $160 each.

c.	Calculate your profit if the exchange rate falls by 10 percent over the next 90 days. (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)
d.	What is the break-even exchange rate? (Do not round intermediate calculations and round your answer to 4 decimal places, e.g., 32.1616.)
