Answer:
$165
Explanation:
According to scenario, computation of data are as follows,
Time required to file on own = 15 hours
Value of own time = $11 per hour
Time required to file by an expert = 2 hours
Tax specialist charges = $55 per hour
So, opportunity cost of preparing own tax = Time required to file on own × Value of own time
By putting vale, we get
Opportunity cost = $11 × 15
= $165
