I'm trying to work out the answer to problem using the dividend discount model.

I'm trying to work out the answer to problem using the dividend discount model.

a) I need to find the value of a stock that pays an annual dividend of $5 and is not expected to grow, with a discount rate of 10%.

b) same calculation but with an expected growth of 5%?

Can you explain the process of finding these answers so I can try it on my own?
