Answer: Option(a) is correct.
Explanation:
Total Revenue = Units sold × price per unit sold
= 11,000 × $75
= $825,000
Explicit cost = Units sold × cost per unit
= 11,000 × $55
= $605,000
Implicit cost = Earning at state university + Entrepreneurial talent + cash bonds at 10% interest
= $45000 + $5,000 + ($100,000 × 10%)
= $60,000
Economic profits = Total Revenue - (Explicit cost + Implicit cost)
= $825,000 - ($605,000 + $60,000)
= $825,000 - $665,000
= $160,000
