Calculate Adirondack's times-burden-covered ratio for next year assuming annual sinking-fund payments on the new debt will equal $20 million. c. Calculate next year's earnings per share assuming Adirondack raises the $63 million of new debt d. Calculate next year's times-interest-earned ratio, times-burden-covered ratio, and earnings per share if Adirondack selis 2.8 milion new shares at $20 a share instead of raising new debt.
