Required: a) compute the ROI for each company.

In other words, compute profit margin and asset turnover for each company: Apple profit margin= , asset turnover= (Enter both as a fraction of 1, not as percentage. I.e., if the profit margin is 0.045 (4.5%) and asset turnover is 3.42 (342%), enter 0.045 and 3.42) Dell profit margin= , asset turnover= If you multiply profit margin * asset turnover, you should get the ROI from part (a) c) Which company has higher profit margin?(1=Apple, 2=Dell) d) Which company has higher asset turnover? 1=Apple, 2=Dell)
