Suppose $1-$year T$-$bills currently yield $\backslash (7\mathrm{.}00\backslash \%\backslash )$ and the future inflation rate is expected to be constant at $\backslash (4\mathrm{.}70\backslash \%\backslash )$ per year. What is the real risk$-$free rate of return, $\backslash ($ r$^\{*\}\backslash )?$ Disregard any cross$-$product terms, i$..$ if averaging is required, use the arithmetic average. $\backslash (2\mathrm{.}12\backslash \%\backslash )\backslash (2\mathrm{.}48\backslash \%\backslash )\backslash (2\mathrm{.}30\backslash \%\backslash )\backslash (2\mathrm{.}81\backslash \%\backslash )\backslash (2\mathrm{.}23\backslash \%\backslash )$
