Assume that a machine hour constraint is binding. if the original amount of machine hour available 200 minutes and the range of feasibility is from 130 minutes providing an additional machine hours will result in a. the same product mix, different total profit b. a different product mix, same total profit as before c. the same product mix, same total profit d. a different product mix, different total profit

Solution

The correct answer choice is d. a different product mix, different total profit.

Because, if the original amount of machine hour available 200 minutes and the range of feasibility is from 130 minutes, then we cannot solve it for same product mix and hence it must get a different total profit.
