Final answer:
To determine the maximum percent of melt demand beyond which Manny's Sandwich Shop (MSS) can no longer fully meet the demand, we need to analyze the flow of the process and the available resources. The maximum percent of melt demand beyond which MSS cannot fully meet the demand is 78.95%.
Step-by-step explanation:
To determine the maximum percent of melt demand beyond which Manny's Sandwich Shop (MSS) can no longer fully meet the demand, we need to analyze the flow of the process and the available resources.
Since the total demand is 9 sandwiches per hour, if the demand for melt sandwiches exceeds a certain percentage, MSS will not be able to meet the demand without overtime.
In this scenario, the maximum percent of melt demand beyond which MSS cannot fully meet the demand is 78.95% (option d).
