Required Rate of Return

Stock R has a beta of $1\mathrm{.}4,$ Stock S has a beta of $0\mathrm{.}55,$ the expected rate of return on an average stock is $11\%,$ and the risk$-$free rate is $4\%.$ By how much does the required return on the riskier stock exceed that on the less risky stock? Do not round intermediate calculations. Round your answer to two decimal places.
