Suppose that the current one$-$year risk$-$free interest rate in the U$.$S$.$ is $2\%$ and the current one$-$year risk$-$free interest rate in Canada is $6\%.$ You also know that the one$-$year forward Canadian dollar$-$euro exchange rate is $0\mathrm{.}625($one Canadian dollar equals $0\mathrm{.}625$ euros$)$ and the one$-$year forward U$.$S$.$ dollar$-$euro exchange rate is $0\mathrm{.}8($one U$.$S$.$ dollar equals $0\mathrm{.}8$ euros$).$ According to covered interest rate parity, what is the current Canadian dollar$/$U$.$S$.$ dollar spot rate $($value of one Canadian dollar in U$.$S$.$ dollars$)?$
