Final answer:
The effective unit margin for Fat-Free Brownies, including the impact of cannibalization, is approximately -$794.37.
Step-by-step explanation:
To calculate the effective unit margin including the impact of cannibalization for the Fat-Free Brownies, we need to consider the original estimate of cannibalization and the variable costs for both the Fat-Free Brownies and the Fudgie brownies.
The effective unit margin can be calculated using the formula:
Effective Unit Margin = (Price - Variable Cost) * (1 - Cannibalization Rate)
Given the information provided, the price of the Fat-Free Brownies is $3.84, the variable cost for the Fat-Free Brownies is $1.66, and the cannibalization rate is 483.28. Plugging in these values into the formula gives us:
Effective Unit Margin = (3.84 - 1.66) * (1 - 483.28)
Performing the calculations, we find that the effective unit margin for Fat-Free Brownies, including the impact of cannibalization, is approximately -$794.37.
