Answer:
required return = 9.32 %
Step-by-step explanation:
given data 
dividend payment = $3.30 per share
growth rate of 2.75 % 
stock currently sells = $50.20 per share
to find out
required return
solution
we will apply here required return formula that is express as 
required return = 
 + g
here D is dividend at the end of year i.e 3.30 and p is price at the beginning i.e. 50.20 and g is growth rate of 2.75% 
so put all these value we get 
required return = 
 + g
required return = 
 +2.75%
required return = 6.57% + 2.75% 
required return = 9.32 %
