Suppose a U$.$S$.$ investor wishes to invest in a British firm currently selling for $34$ per share. The investor has $$6,800$ to invest, and the current exchange rate is $$2$ per $.$

Suppose now the investor also sells forward $3,400$ at a forward exchange rate of $$1\mathrm{.}90$ per $.$

Calculate the dollar$-$denominated returns for each scenario.

Note: Round your answers to $2$ decimal places. Negative values should be indicated by a minus sign.
