Answer:
ME should make the investment because it results in not only higher market share but also a $24,000 increase in profits.
Step-by-step explanation:
Currently ME's marketing expenditures represent 25% of the industry's marketing expenditures and it matches his market share. Using the competitive parity approach, three additional market share points should cost $120,000 ($40,000 for each point) and should increase gross profits to a total of $1,344,000 ($144,000 increase). The difference between incremental revenue and incremental expenses = $144,000 - $120,000 = $24,000.
