Answer:
The benefits are that Aaron will be more productive, which will lead to more output, as well as increased human capital as a result of his videos. The costs to Aaron are the time and money to take the course, along with any forgone income that could have been earned during this time.
Explanation:
If Aaron chooses to take the course, he will become better educated in his work, making economics content. However, the costs he will endure will be the cost of the course itself, the time to learn the new concepts, and the revenue he could have generated from making more videos instead of taking the time off to take the course.
The benefits society will gain if Aaron completes the course is being able to watch better quality videos made by Aaron. The videos will then help workers work more efficiently, increasing productivity and economic growth.
Hope this helps!
