Question 37

The marginal cost of the seventh unit is 13.

The marginal cost of the seventh unit is calculated based on the additional cost incurred from producing one more unit beyond the sixth unit. In this case, the marginal cost is determined to be 13.

A) 13.71

Option A is incorrect because it suggests a marginal cost that exceeds the actual calculated cost for the seventh unit. The value of 13.71 does not align with the data provided regarding costs incurred in producing the units.

B) 7.29

Option B is also incorrect as it represents a significantly lower marginal cost than is accurate for the seventh unit. The figure of 7.29 does not reflect the incremental costs associated with increasing production from six to seven units.

C) 13

Option C is correct, as it accurately represents the marginal cost of producing the seventh unit. This figure reflects the additional cost incurred when moving from the production of six units to seven units, confirming it as the correct answer.

D) 16

Option D is incorrect because it suggests an even higher marginal cost than the calculated value. A marginal cost of 16 does not appropriately reflect the cost structure associated with the production of the seventh unit.

Conclusion

The correct answer is definitively 13, as it accurately represents the marginal cost of producing the seventh unit. Other options fail to provide the correct cost increment, either being too high or too low compared to the established cost for the seventh unit. Thus, Option C stands out as the only valid choice based on the given data.
