$($Real interest rates: approximation method$)$ If the real risk$-$free rate of interest is $3\mathrm{.}9\%$ and the rate of inflation is

expected to be constant at a level of $3\mathrm{.}7\%,$ what would you expect $1-$year Treasury bills to return if you ignore the cros

product between the real rate of interest and the inflation rate?

The expected rate of return on $1-$year Treasury bills is

$\%.($Round to one decimal place.$)$
