Three loaves of bread are required for each wheel of cheese. As a result, option (a) is the proper response.
What was the opportunity cost?
When you choose one course of action over another, you pay an opportunity cost. The difference between the projected returns for each option is the formula for computing an opportunity cost.
[tex]\text{Opportunity Cost} = \frac{\text{Time Taken to make a wheel of cheese}}{\text{Time taken to produce a loaf of bread}} \\= \frac{ 9 \text{hours}}{3 \text{hours}} \\=3[/tex]
Therfore, 3 loaves of bread is the correct answer.
