Hi please help with a$,$ b$,$ c$,$ and d$.$ Kept getting it wrong. Thank you!

Najafi Company. Najafi Company, U$.$S$.-$based manufacturer of industrial equipment, just purchased a Korean company that produces

plastic nuts and bolts for heavy equipment. The purchase price was $7,300$ million Korean won $($KRW$).$ KRW$1,000$ million has already

been paid, and the remaining KRW$6,300$ million is due in six months. The current spot rate is KRW$1,111=$USD$1\mathrm{.}00,$ and the $6-$month

forward rate is KRW$1,169=$ USD$1\mathrm{.}00.$ The $6-$month Korean won interest rate is $15\%$ per annum, the $6-$month U$.$S$.$ dollar rate is $3\mathrm{.}5\%$ per

annum. Najafi can invest at these interest rates, or borrow at $2\%$ per annum above those rates. A $6-$month call option on won with a

KRW$1,200=$ USD$1\mathrm{.}00$ strike rate has a $4\mathrm{.}3\%$ premium, while the $6-$month put option at the same strike rate has a $3\mathrm{.}8\%$ premium. Najafi's

weighted average cost of capital is $10\%.$ Compare alternate ways below that Najafi might deal with its foreign exchange exposure.

a$.$ How much in U$.$S$.$ dollars will Najafi pay in $6$ months without a hedge if the expected spot rate in $6$ months is assumed to be

KRW$1,111=$ USD$1\mathrm{.}00?$ KRW$1,169=$ USD$1\mathrm{.}00?$

b$.$ How much in U$.$S$.$ dollars will Najafi pay in $6$ months with a forward market hedge?

c$.$ How much in U$.$S$.$ dollars will Najafi pay in $6$ months with a money market hedge?

d$.$ How much in U$.$S$.$ dollars will Najafi pay in $6$ months with an option hedge if the expected spot rate in $6$ months is assumed to be less

than KRW$1,200=$ USD$1\mathrm{.}00?$ To be KRW$1,300=$ USD$1\mathrm{.}00?$
