What type of decision making occurs when you turn off the bedroom light to save money on your electric bill?

The correct answer, marginal decision making, focuses on the concept of evaluating the additional benefits and costs of a particular action or decision. In the context of turning off the bedroom light to save money on your electric bill, you are weighing the marginal cost of leaving the light on (increased electricity usage and costs) against the marginal benefit of having the light on (increased visibility and comfort). The decision to turn off the light implies that the additional savings from not using electricity outweigh the benefits of keeping the light on for that extra time.

Marginal decision making is centered around the principle of making choices based on the incremental changes in resources. In this scenario, by assessing the cost savings from reducing electricity consumption, you are effectively engaging in marginal analysis, determining whether the benefit of saving money justifies the cost of potentially reduced convenience from a dimly lit room.
