For each of the four firms below (CAT, DOG, FERRET, and ALPACA), use the given values to solve for the missing values. Notes: We are equating ROA and ROI in this problem; see page 1090 of your text. You may assume that balances for total assets, etc. are averages, when necessary, and that sales are net sales. Assume that "invested capital" = total assets. Assume that the tax rate for all firms is 20%, and that the weighted average cost of capital is the minimum acceptable return
