$($Real

interest$$rates: approximation

method$)$

If the real$$risk$-$free rate of interest is

$4\mathrm{.}8\%4\mathrm{.}8\%$

and the rate of inflation is expected to be constant at a level of

$3\mathrm{.}1\%3\mathrm{.}1\%,$

what would you expect$1-$year Treasury bills to return if you ignore the cross product between the real rate of interest and the inflation$$rate$?$
