One of the options is Delta Airlines. They have paid an annual dividend of $$4\mathrm{.}94$ for the past $25$ years and we expect them to continue this indefinitely. Assuming the market requires a$($n$)13\mathrm{.}9\%$ return from Delta, what is the value of a share of stock? $($Hint: Round intermediate calculations and answer to $2$ decimal places$)$

$$35\mathrm{.}54$

And what if we assumed they would start increasing their dividend by $3\mathrm{.}9\%$ per year? What would be a fair price to pay in

And what if we assumed they would start increasing their dividend by $3\mathrm{.}9\%$ per year? What would be a fair price to pay in that scenario? $($Hint: Round intermediate calculations and answer to $2$ decimal places$)$

$$51\mathrm{.}33$

Hint $-$ Use the constant growth model

I need help with the second question I keep getting it wrong. The first question is needed information.
