Answer:
Option D : $20
Step-by-step explanation:
The average total cost to produce 100 oatmeal cookie = $0.25 per cookie.
So, total cost for 100 cookies will be = [tex]0.25\times100=25[/tex] dollars
The company’s marginal cost is constant at $0.10 for all oatmeal cookies produced.
When 50 cookies are produced, the marginal cost will be = [tex]0.10\times50=5[/tex]dollars
The total cost to produce 50 oatmeal cookies = [tex]25-5=20[/tex] dollars
Hence, option D is correct.
