Answer: 13.61%
Step-by-step explanation:
The Security Market Line is the Capital Asset Pricing model graphed the required return can be found using CAPM.
= Risk free rate + beta ( Market return - risk free rate)
Use the longer term rates for CAPM so use the T bond rate of 5.25% for risk free rate and use the 14.75% for the market return.
= 5.25% + 0.88 * ( 14.75 - 5.25%)
= 13.61%
