Marginal cost of producing the third lawnmowers:

d. $100

Step-by-step explanation:

Harvey's marginal cost for producing the third unit of lawnmowers is the additional cost that resulted when the total cost increased from $200 to $300. However, it can be deciphered from the case that the marginal cost for Harvey, which it is supposed to be a variable cost, is traceable to the direct labor costs. This implies that the fixed cost element for Harvey in the production of the lawnmowers has been relatively fixed at $100. It does not vary with the volume of production, while the direct labor costs vary with the volume of lawnmowers produced by Harvey.
