Please help me answer this multiple step question.

A.) You're analyzing the stock of a certain company. The most recent dividend paid was $5 dollars per share. The company's discount rate is 8%, and the firm is expected to grow at 4% per year forever. What is the dividend yield of this stock?

B.) Assume a corporation has just paid a dividend of $ 1.84 per share. The dividend is expected to grow at a rate of 2.4% per year forever, and the discount rate is 8%.

What should be the amount paid as a dividend per share next year?

C.) Assume that the Pure Expectation Theory determines interest rates in the markets. Today's market rates for different maturities are as follows:

1 year = 3.2%

2 years = 4.3%

3 years = 5.8%

4 years = 6.6%

5 years = 7.9%

What is the implied 2 year interest rate for investing in 3 years?
