Answer:
The correct answer is option (D).
Explanation:
According to the given scenario, given data are as follows:
Production with two workers = 1,000 bushels
Production with four workers = 1,300 bushels
Hence, the marginal product of the fourth worker can be calculated by the following formula:
Marginal Product of Labor ( MPL ) = Change in output quantity / Change in labor quantity
MPL = ( 1300 - 1000 ) / ( 4 - 2 )
MPL = 300 / 2
MPL = 150
Therefore, the marginal product of the fourth worker is 150 bushels.
