Answer:
Zero opportunity cost
Step-by-step explanation:
Opportunity cost in business is defined as the value of an alternative forgone to arrive at a more favorably valued option in the course of making a decision. Opportunity cost is necessary as every alternative is considered to have alternative usages.
However , in a situation where no alternative option is given up in arriving at a particular decision , or the given up alternatives have no value to you, it is said that the selected decision comes with no opportunity cost , that is it has a zero opportunity cost.
As Monica could still afford to bake five pies in three hours without giving up the production of any cakes , the production of pies had zero opportunity cost.
