Guaranty Bank believes the New Zealand dollar $($NZ$$)$ will depreciate over the next five days from $$\mathrm{.}50$ to $$\mathrm{.}48.$ The following annual interest rates apply:

Currency Lending Rate Borrowing Rate

Dollars $7\mathrm{.}10\%7\mathrm{.}50\%$

New Zealand dollar $($NZ$$)6\mathrm{.}80\%7\mathrm{.}25\%$

Guaranty Bank has the capacity to borrow either NZ$$10$ million or $$5$ million. If Guaranty Bank's forecast is correct, how shall Guaranty Bank implement its speculating trading activities and what will its dollar profit be from speculation over the five$-$day period $($assuming it does not use any of its existing consumer deposits to capitalize on its expectations$)?(30/360$ convention used for the interest calculation, i$.$e$.,$ assuming $360$ days a year$)$
