All our Data Science projects include bite-sized activities to test your knowledge and practice in an environment with constant feedback.
All our activities include solutions with explanations on how they work and why we chose them.
The recession just hit! Let's say you need to subtract $50B from all the companies in revenue_in_billions. Store the new series in the variable revenue_recession
The accounting team needs more detail when calculating EBITDA. They need revenue expressed in dollar units (instead of millions or billions). Use either series revenue_in_millions or revenue_in_billions to create a new series revenue_in_dollars.
Using the series number_of_employees (given in the notebook), your job is to calculate revenue per employee, expressed in dollars (units). Store it in the variable revenue_per_employee.
