HR Industries (HRI) has a beta of 1.2, while LR Industries' (LRI) beta is 0.6. The risk-free rate is 6%, and the required rate of return on an average stock is 13%. The expected rate of inflation built into rRF falls by 1.5 percentage points; the real risk-free rate remains constant; the required return on the market falls to 10.5%, and all betas remain constant. After all of these changes, what will be the difference in the required returns for HRI and LRI? (Round to two decimal places)

I got my answer 7.80%. Is that correct?
