How did the Sapa Inca influence the Incan economy? How did the road system influence the economy?

1-The Sapa Inca was the absolute ruler of the empire and accumulated in his power the political, social, military, and economic direction of the State.2-The important relationship between prices and economies of scale has pointed out the importance of transport leading to the introduction of transport activity in economic policy debates.

Explanation:

1- He ordered and directed the construction of great engineering works, such as Sacsayhuaman, a fortress that took 50 years to complete; or the urban plan of the cities. However, among their most notable works was the network of roads that crossed the entire empire and allowed a rapid journey for the administrators, messengers and armies provided with hanging bridges and tambos.2-Early years of 20th century reveal a new type of economic analysis of the transport market based on the principle of sustainable development. Transition of transport sector to another level of development has being pursued specific transport market developments by investigating concomitant of economic, environmental and social influences. In the presented paperwork the authors identify role of transport in developing a sustainable economy that will provide, in the near future, new services, ensuring better management and real-time traffic capabilities in order to protect the environment and offer safety

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).
