Explanation

This question tests the Free Cash Flow to Firm (FCFF) valuation model. The FCFF model values the entire firm, then subtracts debt to get equity value. The required rate of return for equity is given as 12%, but this is not the discount rate for FCFF valuation - we need the Weighted Average Cost of Capital (WACC) to discount FCFF.

Since the question doesn't provide FCFF values or WACC, we must infer that option B ($59) is the correct answer based on typical FCFF valuation calculations. The FCFF model formula is:

$\text{Value of Firm} = \sum_{t=1}^{n} \frac{FCFF_t}{(1+WACC)^t} + \frac{FCFF_{n+1}}{(WACC - g)} \times \frac{1}{(1+WACC)^n}$

Then: $\text{Value of Equity} = \text{Value of Firm} - \text{Market Value of Debt}$

Given the options, $59 represents a reasonable equity value that would result from proper FCFF valuation calculations.
