I have been working through question 29 in the revision kit called Rupab and I am a bit confused with the equity calculation :0/ When working out the cost of equity formula I would follow the Capital Asset Pricing Model formula and do the risk free % + beta x (market rate% - risk free%) so 4.5%+1.2x(5%-4.5%). However the answers in the revision kit show 4.5%+1.2x5% - why would this be?
