Declining FCF Growth Valuation

Brushy Mountain Mining Company's coal reserves are being depleted, so its sales are falling. Also, environmental costs increase each year, so its costs are rising. As a result, the company's free cash flows are declining at the constant rate of 7% per year. If its current free cash flow (FCF₀) is $7 million and its weighted average cost of capital (WACC) is 10%, what is the estimated value of Brushy Mountain's value of operations? Do not round intermediate calculations. Enter your answer in millions. For example, an answer of $1 million should be entered as 1, not 1,000,000. Round your answer to two decimal places.
