This is a straightforward break-even analysis case requiring candidates to calculate how many locations are needed to cover fixed costs ($1M) and variable labor costs ($200k per location). The key is to work backwards from revenue (50 trainees × $500/month × 12 months = $300k per location) minus labor costs to find the break-even point of 10 locations. Strong candidates will also contextualize the business by noting limited customer lifetime value (1-2 years), minimal capex requirements, and high scalability potential.
