Suppose your company imports computer motherboards from Singapore. You have just

placed an order for $30,000$ motherboards at a cost to you of $148\mathrm{.}25$ Singapore dollars

each. You will pay for the shipment when it arrives in $90$ days. You can sell the

motherboards for $$147$ each. The current exchange rate is $$$\frac{1\mathrm{.}1097}{\text{\$}}.$

a$.$ What is your profit at the current exchange rate? $($Do not round intermediate

calculations and round your answer to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$

b$.$ What is your profit if the exchange rate goes up by $10$ percent prior to the shipment's

arrival? $($Do not round intermediate calculations and round your answer to $2$

decimal places, e$.$g$.,32\mathrm{.}16.)$

c$.$ What is your profit if the exchange rate goes down by $10$ percent prior to the

shipment's arrival? $($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$.,$

$32\mathrm{.}16.)$

d$.$ What is the percentage change in the exchange rate that would result in a break$-$even

profit? $($A negative answer should be indicated by a minus sign. Do not round

intermediate calculations and enter your answer as a percent rounded to $2$ decimal

places, e$.$g$.,32\mathrm{.}16.)$
