How would you decide how many shows to produce and what subscription price to set for an online-content startup? Lay out: a) an optimization objective (e.g., maximize monthly profit or LTV) and constraints (budget, price cap at $20, production lead times); b) the minimum data you need (demand elasticity to price and content, engagement lift per show, acquisition curve, churn); c) how you would estimate that data (A/B tests, conjoint analysis, holdout-based uplift modeling); and d) how your recommendation would change if variable cost increased from $4 to $6 per subscriber per month.
