Suppose we are facing making an investment in one of two projects: Project A and Project B. Information about the projects follow:

Project A Project B

Sales price per unit $30 $30

Variable cost per unit $12 $5

Total fixed cost $200,000 $300,000

At what sales volume will Project A just cover the opportunity cost of selecting Project B? This seems to me the same question as "where are the profits from the two projects equal?"
