Quizplus · Accepted Answer

The marginal product of land is the change in output that results from adding one extra unit of land. To find it, we can look at the difference in output between using 3 and 2 square feet of land:

Marginal product of land = (Output from 3 sqft) - (Output from 2 sqft) 
Marginal product of land = 41 - 32 
Marginal product of land = 9

Therefore, the answer is B. Mark can increase his output by 9 units by adding one more square foot of land when he has already used 2 square feet of land.
