Answer:
$36
Explanation:
The Opportunity cost refers to the benefit that is sacrificed by choosing some other alternative.
Therefore, the opportunity cost of going to the concert is the loss of money income that he would earned otherwise.
Benefit received from the concert = $35
Hence,
The amount of sacrificed wages is as follows:
= Income form working on Saturday - Psychic cost
= (4 hours × $11/hr) - (4 hours × $2/hr)
= $44 per hour - $8 per hour
= $36
The opportunity cost of going to the concert is $36.
