Answer:
$101.82
Step-by-step explanation:
the intrinsic value of the stock can be determined by determining the value of the stock using the constant growth dividend model 
according to the constant dividend growth model 
price = d1 / (r - g) 
d1 = next dividend to be paid 
r = required return 
g = growth rate 
growth rate = retention rate x ROE 
Retention rate = 1 - payout ratio = 1 - 0.4 = 0.6 
0.6 x 20% = 12%
dividend = 0.4 x $10 = $4 
the required return can be determined using the capital asset price model: Expected rate of return = risk free + beta x (market rate of return - risk free rate of return)
0.08 + 1.2(0.15 - 0.08) = 0.164 = 16.4%
Intrinsic value = 4 ( 1.12) / (0.164 - 0.12) = 4.48/0.044 = $101.82
