HEL ILL GIBE THE CROWN THINGY THING 4. The developments described in the excerpt best illustrate which of the following?

“[A]nnexing Texas had meant the addition to the Union of a huge southwestern state where slavery was legal, and slavery’s spread was something to which large numbers of Northerners were emotionally and politically opposed. This opposition increased and began to be more strident during the War with Mexico, which many in the North regarded as a war brought on largely by southern expansionists. Hostilities officially ended in February of 1848 with the Treaty of Guadalupe Hidalgo, as a result of which approximately one-fifth of the United States of 1849 was acquired by the victors. . . .”

Explanation:

marginal cost is a microeconomic measure that us to evaluate the extent to which the level of production of a good is sustainable in accounting, that is, to how many quantities the company plans to profit from the production of the good.

the concept of marginal cost is simple, it means the cost of producing one more item. for example, in the case of pies, the marginal cost is the cost of producing one more pie than those that have already been produced.

it is important to understand that productive activity influences marginal cost. the marginal cost of some goods can be very high, while others may be insignificant. for example, the marginal cost of producing an extra plane is very high. already the marginal cost of a water company to provide 1l more water is derisory.

in the case of pies, the cost involves the inputs, the labor and the fixed cost, which involves the fixed space of the bakery. the level of production initially has the marginal cost decreasing because there is space and manpower available. however, to produce more you have to hire more workers and buy more inputs. if physical space is limited, workers will conflict with places, inputs and their productivity will decrease, meaning there is an optimum point of production for each level of space and manpower. from this point on, the productivity of the workers will be getting smaller because of lack of space, so that the marginal cost of producing one more pie will be increasing. so, although you have not posted the chart, but if you have the answer, you can see that my explanation goes according to the marginal cost curve that will increase from the 4th pie, answer (c).
