Calculate the intrinsic value of Rio Tinto shares using the free cash flow model of Spreadsheet 18.2. Treat each scenario independently. a. Rio Tinto's P/E ratio starting in 2022 (cell G3) will be 11. (Round your intrinsic value to the nearest whole number and per share value to 2 decimal places.) b. Rio Tinto's unlevered beta (cell B22) is 1.2. (Round your intrinsic value to the nearest whole number and per share value to 2 decimal places.)
