Calculate the following ratios for 2018 and 2019. Since 2017 numbers are not presented, do not use averages when calculating the ratios for 2018. Instead, use the number presented on the 2018 balance sheet.

1. Net margin. (Round your answers to 2 decimal places.)
2. Return on investment. (Round your answers to 2 decimal places.)
3. Return on equity. (Round your answers to 2 decimal places.)
4. Earnings per share. (Round your answers to 2 decimal places.)
5. Price-earnings ratio (market prices at the end of 2018 and 2019 were $11.88 and $9.54, respectively). (Round your intermediate calculations and final answers to 2 decimal places.)
6. Book value per share of common stock. (Round your answers to 2 decimal places.)
7. Times interest earned. Exclude extraordinary income in the calculation as they cannot be expected to recur and, therefore, will not be available to satisfy future interest payments. (Round your answers to 2 decimal places.)
8. Working capital.

10. Quick (acid-test) ratio. (Round your answers to 2 decimal places.)
