Answer:
$100
Explanation:
Opportunity cost refers to the benefit that is sacrificed by selecting some other option or alternative.
Loss of money income:
= 5 hours × $8 per hour
= $40
Expenses for attending the concert:
= Ticket price + Parking cost
= $40 + $20
= $60
Therefore, the opportunity cost of attending the concert is as follows:
= Wages that would have been earned + Expenses to attend the concert
= $40 + $60
= $100
