Aunt Kathleen owns 3000 preferred shares of ABC Inc., and she is thinking of selling 100 of these shares to pay for a new computer. These shares pay a stable quarterly dividend of $0.65 per share (i.e., there will be four dividend payments in a year, and each payment is $0.65 per share). Aunt Kathleen's required return is 12% APR compounded semi-annually.

1. What is the effective annual return (EAR) based on an APR of 12% compounded semi-annually?(1 mark)
2. What is the effective return per dividend payment period for Aunt Kathleen?(1 mark)
3. What is the estimated stock price based on the Constant Dividend model?(2 marks)
4. What is the maximum amount of money that Aunt Kathleen can spend on the new computer if she only uses the receipts from the sale of 100 shares of ABC's preferred shares to pay for it?

I am requiring help with question number 3 please. I know that the formula for this would be P=D/R but having an issue of what R would be. For question number 1 my answer was 12.36%. For question number 2, I have an answer of 82.63%. but I am not confident in this answer. Your advise would be appreciated.

Thank You
