T$-$bond

Suppose the real risk$-$free rate is $1\mathrm{.}50\%,$ the average future inflation rate for the next $5$ years is $2\mathrm{.}25\%.$ The maturity premium increases by $0\mathrm{.}4\%$ per year starting from time $1,1..$ MRP $=0\mathrm{.}4\%(t-1),$ where $t$ is the years to maturity. What rate of return would you expect on a S$-$year Treasury security?
