Answer:
400%
Step-by-step explanation:
The Brand Development Index (BDI) is determined as the percentage of Brand sales in a particular market (800) from total sales (2,000) divided by the percentage of the population of a particular market (100 Oreo cookie lover lawyers) from the total population (1,000 lawyers):
[tex]BDI = \frac{\frac{800}{2,000} }{\frac{100}{1,000}}*100\%\\ BDI=400\%[/tex]
The BDI for Oreo cookies consumed by lawyers is 400%.
