Answer: The Multiconcept restaurant is beneficial to both restaurant chains
Explanation:
If they share resources then they are saving 30% in fixed costs even though they are losing 20% in sales.
If the losses in sales are subtracted from the savings in fixed costs, it means that both Taco Bell and KFC are benefitting by 10%.
This shows that the decision to open a shared facility versus two separate facilities is beneficial to both restaurants on a net benefits basis as the savings in fixed costs from sharing facilities outweighs the losses in sales probably resulting from not offering a full menu.
