Answer:
$150,000
Step-by-step explanation:
Amount paid after project completion was =$50,000
The sales revenue for the new company = $550,000
Total deductions =$(250,000+70,000+30,000)=$350,000
Economic profit is the difference between the earned revenue from sell of outputs and cost of all inputs used and any opportunity costs.
In this case, opportunity cost will be the amount received by the web designer after the quit of the project.
Economic profit = $550,000 - $350,000-$50,000 = $150,000
