Calculation of Return on Total Assets:
Return on Total assets can be calculated using the following formula:
Return on Total Assets = Net Income / Total Assets
We can calculate Net income as follows:
Sales $2960
Less: Operating Costs $2675
Less: Interest charges $125
Income before tax = 160
Less: Tax (160*40%) = 64
Net Income = $96
Hence , Return on Total Assets = 96/2100 = 0.0457 =4.57%
