**Required:**

1. Compute the gross profit percentage for each year (rounded to one decimal place). Assuming that the change from 2015 to 2016 is the beginning of a sustained trend, is Computer Tycoon likely to earn more or less gross profit from each dollar of sales in 2017?

3. Computer Tycoon reported average net fixed assets of $54,200 in 2016 and $45,100 in 2015. Compute the fixed asset turnover ratios for both years (round to two decimal places). Did the company better utilize its investment in fixed assets to generate revenues in 2016 or 2015?

4. Computer Tycoon reported average stockholders’ equity of $54,000 in 2016 and $40,800 in 2015. The company has not issued preferred stock.
