Answer / Explanation:
To answer this question considering the tax entity and how Janice will report this information on her individual tax return, We need to consider the fact that different tax entity are categorized by its unique report and information.
So to properly answer these question, we will have to assume three (3) different scenario which are: (1) Is it a Limited Liability Company, Is it a Small business corporation, Is it an AC Corporation.
We should also note that this segregation is need as each type of corporation tax are dealt with differently thus enabling us treat the question properly in respect to tax entity and as regards to how Janice will report the information on her individual tax return.
Consequentially, 
a. If Catbird Company is an LLC: A single-member LLC is taxed as a proprietorship. Thus, Janice will report the $100,000 operating income (Schedule C), $15,000 long-term capital gain (Schedule D), and if she itemizes, $5,000 charitable contribution (Schedule A) on her tax return. The $70,000 withdrawal would have no effect on Janice's individual tax return.
b. If Catbird Company is an S corporation: An S corporation is a tax reporting entity (Form 1120S), and its income, gains, deductions, and losses are passed through to and reported by the shareholders on their tax returns. Separately stated items (e.g., long-term capital gain and charitable contribution) retain their character at the shareholder level. Consequently, Janice will report the $100,000 operating income (Schedule E), $15,000 long-term capital gain (Schedule D), and if she itemizes, $5,000 charitable contribution (Schedule A) on her tax return. The $70,000 withdrawal would have no effect on Janice's individual tax return.
c. If Catbird Company is a C corporation: A C corporation is a separate taxable entity, and its taxable income has no effect on the shareholders until such time a dividend is paid. When dividends are paid, shareholders must report dividend income on their tax returns. Thus, Catbird Company will report taxable income of $110,000 ($100,000 operating income + $15,000 LTCG - $5,000 charitable contribution) on its Form 1120. Corporations receive no preferential tax rate on long-term capital gains. Janice will report dividend income of $70,000 (Schedule B) on her individual tax return.
 
        
             
        
        
        
Answer:
Yes, Stock A has higher dividend yield
Explanation:
given data 
market risk premium = 6.0%
risk-free rate = 6.4%
                                                        A                                        B
Beta                                                1.10                                    0.90
Constant growth rate                    7 %                                     7%
to find out
does stock A has higher dividend yield than Stock B
solution
we get here Stock A rA = 6.4% + 1.1 × 6% 
Stock A rA  = 13.00%
and
Dividend yield of stock A = rA - g 
Dividend yield of stock A = 13.00% - 7% 
Dividend yield of stock A  = 6% 
and
for Stock B rB = 6.4%+ .9 × 6% 
Stock B rB = 11.80%
and
Dividend yield of stock B = rA - g 
Dividend yield of stock B  = 11.80% - 7% 
Dividend yield of stock B = 4.80% 
so we can say Yes, Stock A has higher dividend yield
