Questions: Multiple Select Question Select all that apply A student is deciding whether to take an additional class or work extra hours. Which amounts are relevant to this decision? (Check all that apply.) out-of-pocket costs opportunity costs sunk cost

The relevant amounts for the student's decision are:

1. Out-of-pocket costs: These are the direct expenses that the student would incur by taking the additional class, such as tuition fees, textbooks, and other materials. These costs are relevant because they directly impact the student's financial situation.

2. Opportunity costs: This refers to the potential benefits the student foregoes by choosing one option over another. In this case, the opportunity cost of taking the additional class would be the income the student could have earned by working extra hours. Conversely, the opportunity cost of working extra hours would be the educational benefits and potential future earnings from taking the additional class.

Sunk cost is not relevant to this decision. Sunk costs are past expenses that have already been incurred and cannot be recovered. Since these costs cannot be changed by the current decision, they should not influence the student's choice.

In summary, the relevant amounts are:

• Out-of-pocket costs
• Opportunity costs
