2. Diseconomies of scale: This occurs when a percentage increase in input by a firm leads to less percentage increase in its output.
3. Constant returns to scale: This occurs when a percentage increase in by a firm input leads to an equal percentage increase in its output.
From the question therefore, we have:

b. Outputs increase by less than 15 percent: The firm experiences diseconomies of scale since a 15 percentage increase in its input leads to a lsess than 15 percentage increase in its output.
c. Outputs increase by greater than 15 percent: The firm experiences economies of scale since a 15 percentage increase in its input leads to an a greater percentage increase in its output.
