Burger Profit Mix — Scenario A vs. Scenario B

Context: You sell two burger types (Regular and Vegan). In Scenario A, you sell only Regular. In Scenario B, you sell both with a mix ratio Vegan:Regular = 2:3. Total units sold are the same in both scenarios.

Total units sold unchanged between scenarios

Compute:

The average profit per burger in Scenario A and in Scenario B.
The difference (B − A) in $ per burger.
The total profit change for 1,000,000 total burgers (B minus A).
