$5$$IUS$$.$ You have just placed an order for $36,000$

motherboards at a cost to you of $231\mathrm{.}05$ Singapore dollars

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

days. You can sell the motherboards for $$161$ each.

b$.$ Calculate your profit if the exchange rate rises by $11$

percent over the next $90$ days.

Note: Do not round intermediate calculations and

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

c$.$ Calculate your profit if the exchange rate falls by $11$

percent over the next $90$ days.

Note: 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 break$-$even exchange rate?

Note: Do not round intermediate calculations and

round your answer to $4$ decimal places, e$.$g$.,$

$32\mathrm{.}1616.$

e$.$ What percentage decrease does this represent in

terms of the Singapore dollar versus the U$.$S$.$ dollar?
