Hello, I'm having trouble figuring this out. Can you help me and show me the formula to come to the conclusion?

Thames Inc.'s most recent dividend was $2.6 per share (D₀ = $2.6).The dividend is expected to grow at a rate of 5% per year.The risk-free rate is 4% and the return on the market is 10%.The company's beta is 1.5

What is the required rate of return on the stock, k_s?

What is the price of the stock today, P₀?

What is the price of the stock three years from now, P₃?

Unfortunately for some reason I cannot open links. Sorry.
