i noticed in the BPP revision kit when calculating the cost of equity using CAPM they do not deduct the risk free rate from the market premium. For e.g. Q 57 to establish the cost of equity they simply do 3.8 1.2 x 7 = 12.2. Whereas I calculate by deducting 3.8 from 7 giving me a completely different cost of equity. Please advise.
