A.

6.00

B.

12.00

C.

14.00

D.

18.00

Correct answer is B

Company calculates marginal revenue by dividing the change in total revenue by the change in total output quantity. 

changes in total revenue = 80 - 68 = 12

change in output = 1

therefore 12/1 = 12

so when total revenue is 80, the marginal revenue would be 12

outputs in units total revenue in N Average revenue in N marginal revenue in N
1 20 20 20
2 38 19 18
3 54 18 16
4 68 17 14
5 80 16 12
