Final answer:
Moretti should utilize variable inputs to increase ingredients and staff in preparation for the expected demand surge during Halloween, ensuring efficient operations and customer satisfaction.
Step-by-step explanation:
Given the expected increase in demand for Halloween, Moretti should consider adjusting his staffing based on variable inputs, which are resources that can be altered in the short term. He could increase his orders for ingredients, as these are easily adjusted with a simple phone call. Furthermore, Moretti can scale up staffing by quickly hiring additional workers to manage the front counter and assist with the increased customer flow. This approach allows for flexibility in accommodating the higher demand without overcommitting resources if the demand fluctuates.
