Using Tesla's 2019 10K (linked below) calculate the profit margin, basic earning power (BEP), return on assets (ROA) and return on equity (ROE).How do ROA and ROE differ in the information they convey?Is one or the other a better indicator of company performance and why?

Profit margin on sales = Net income/Sales

Basic earning power (BEP) = EBIT/Total assets

ROA = Net income/Total assets

ROE = Net income/Common equity
