Answer:
c. $240,000
Explanation:
Her economic profit is given by her revenue deducted by the explicit costs (I=$150,000) and implicit costs (opportunity cost).
Her monthly revenue is:
[tex]R=1,000\ (items/day)*30\ days*\$15/item\\R = \$450,000[/tex]
Her opportunity cost is:
[tex]O = 30\ days* 8\ (hours/day)*\$250/hour\\O=\$60,000[/tex]
Her economic profit is:
[tex]P = R-I-O\\P=\$450,000-\$150,000-\$60,000\\P=\$240,000[/tex]
The answer is c. $240,000.
