Explanation:

Detailed explanation-1: -Shelby is an entrepreneur who has decided to open a small advertising firm. She rents office space at a cost of \$25, 000 per year, she has employed an assistant at a salary of \$30, 000 per year, and she incurs annual utility and office supply expenses of \$20, 000.

Detailed explanation-2: -If increasing output reduces the per unit cost, the firm is experiencing economies of scale (which means larger plant sizes have lower average total costs at their respective minimum points) .

Detailed explanation-3: -In the short run, when the output of a firm increases, its average fixed cost decreases. Fixed cost remains same irrespective of number of output produced. So, with increase in output, Fixed cost contribution decreases per unit.

Detailed explanation-4: -Profits are therefore maximized when the firm chooses the level of output where its marginal revenue equals its marginal cost.
