##### Scenario
Estimating incremental customers needed to justify partnership marketing spend.
##### Question
a) If an annual campaign with the ride-sharing partner costs $25 million, how many incremental cardholders are required to at least break even? b) Assuming instead a variable cost of $40 per new customer per year and a one-time marketing spend of $11.8 million, how many new customers are needed to achieve the annual profit calculated in Question 2?
##### Hints
Use per-customer annual profit figure from Question 2; include new variable cost where applicable.
Quick Answer: This question evaluates unit economics and break-even analysis skills, requiring algebraic reasoning about per-customer profit versus fixed and variable marketing costs and is relevant for data scientists analyzing customer acquisition ROI.
