The opportunity cost of attending the Hives concert is $4040
Explanation:
To calculate the opportunity cost we have to determine the benefit that we would forgo by attending the hives concert. Since I don't occur no additional fee to attend the hives concert, the opportunity cost is the forgone benefit of attending the Colbert concert.
As we value attending the Colbert concert at $7070 but we have to pay only $2525 our net benefit will be
[tex]\$8080 - \$4040 = \$4040[/tex]
Therefore, the opportunity cost is $4545 for attending the hives concert.
