The cost of equity using the DCF method: 4.39%.
The cost of equity using the SML method: 15.01%.
Explanation:
a. The cost of equity using the DCF method:
We have: Current stock price = Next year dividend payment / ( Cost of equity - Growth rate) <=> Cost of equity = Next year dividend payment/Current stock price + Growth rate = 0.3 x 1.04/80 + 4% = 4.39%.
b. The cost of equity using the SML method:
