McCue Mining Company's ore reserves are being depleted, so the firm's sales are falling. Also, its pit is getting deeper each year, so its costs are rising. As a result, the company's earnings and dividends are declining at the constant rate of 5 percent per year:
If Do = $5 (supposed to read D sub 0 or the most recent dividend which already has been paid) and ks = 15% (supposed to read K sub s or the minimum acceptable or required rate of return on the stock), then what is the value of McCue Mining's Stock?
