Which of the families engages in subsistence agriculture? 1.The family produces only enough food from its garden to live on 2.The entire family works for minimum wage on a pineapple plantation 3.The entire family weaves straw mats and sells them in the local market 4.The family grows wheat commercially on 6,000 acres of land

1. The family produces only enough food from its garden to live on.

Explanation:

Agriculture could be practiced on a subsistence or commercial scale. Subsistence agriculture is the type of agriculture practiced when the farmer wants to produce just enough output ( in this case, crops and livestock) for his family. Commercial Agriculture is agriculture practiced on a large scale and sold to make profit.

So, the family that produces only enough food from its garden to live on is practicing subsistence agriculture. The family barely makes profit from this type of agriculture.

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).
