I only need help with calculating Market Cap. the current answer of $3,553,360,656 keeps coming back as incorrect.

You are evaluating the stock of Duff Beer, and you have decided to use free cash flows to the firm and free cash flow to equity as your two models. You project that next year Duff will have EBIT of $681 million, depreciation expense of $89 million, capital expenditure of $92 million, and an increase in net working capital of $47 million. Duff has no debt, and the company is not expected to add debt in the foreseeable future. Because there is no debt, there is also no interest expense. Duff's tax rate is 29%, its cost of equity is 13.7%, and its weighted average cost of capital is 13.7%. You project that free cash flows to the firm will grow at 1.5% indefinitely, and that free cash flows to equity will grow at 1.5%. If Duff has 198 million shares outstanding, what is the most you would pay for a share? ( 30 points total)
