Derive the condition under which adding the Vegan burger increases total profit, given: Regular unit margin $3, Vegan unit margin $2, fixed vegan costs F (training + supplier retainer), and cannibalization rate c (fraction of Vegan sales that would have been Regular). Express the break-even Vegan unit sales as a function of F and c, interpret edge cases (c = 0 and c = 1), and describe how you would estimate c in practice.

This question evaluates a data scientist's competency in profit-impact modeling, break-even analysis, and accounting for cannibalization effects using unit contribution margins and fixed costs.

Profit Impact of Introducing a Vegan Burger

Context

A restaurant is considering adding a Vegan burger alongside its existing Regular burger. The unit contribution margins are:

Regular burger margin: $3
Vegan burger margin: $2

Launching Vegan incurs a fixed cost F (e.g., training and supplier retainer). Let c be the cannibalization rate: the fraction of Vegan sales that would otherwise have been Regular sales (i.e., substitution rather than incremental).

Tasks

Express the break-even Vegan unit sales V_BE as a function of F and c.
Interpret the edge cases c = 0 and c = 1.
Describe how you would estimate c in practice.
