In equilibrium, group of answer choices the ratio of marginal benefits to income should be identical across all goods the ratio of marginal benefits to price should be identical across all goods the ratio of total benefits to price should be identical across all goods the ratio of total benefits to income should be identical across all goods

the ratio of marginal benefits to price should be identical across all goods.

Explanation:

In equilibrium, the ratio of marginal benefits to price should be identical across all goods.

marginal benefit is the the maximum amount of money a customer is willing to pay for an additional good or service. The consumer satisfaction tend to decrease as the consumption increases. And for equilibrium to exist  the ratio of marginal benefits to price should be identical across all goods

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

reserve is the answer
