O Marginal cost is the money paid for producing one more unit of a good. Marginal revenue is the money earned from selling

Explanation:

The marginal cost means that the cost has increased, mean it'll change, which means that the quantity of the product being produced has increase by one or more.

on the other hand, Marginal rain is where the revenue has also increased by one or more. so the additional revenue on the product means that the good will be equal to the sell price that the firm charges for the buyer.

Therefore, it'll be option 3 (I think)

Hope this helps!! have a nice day :)

every society, in order to meet the needs of it's people, has to answer three basic questions:

- what should we produce?

- how should we produce it?

- for whom should we produce it?

this questions must be answered in order to, option b, aid in production decisions.

every country can't produce everything, no matter how rich their land is. it may be a matter of technology, resources or geographical conditions. so, these three questions must be resolved in order to get the most of the production of each land.

hope this !
