B. How has Tesla's business strategy (or target customer) changed over time? (4 points) Did the release of a more affordable Model 3 in 2017 change Tesla's Gross Profit Margin and Inventory Tumover? To answer this question, you will have to look at these 2 variables, but specifically for Tesla: - Gross margin: the (gross) profit in percentage that the company eams for each car sale - Inventory turnover: how many times the company sold its stock of inventory in the year You will have to break down how these variables change from year-to-year. Alternatively, you can divide the sample into pre-2017 and post-2017 and compare the average Gross Profit Margin and Inventory Tumover
