Answer:
$50,000,000
Explanation:
You want to know the total output (real gdp) of 1000 workers, each working 2500 hours producing real output of $20 per hour.
GDP
The output, called "gross domestic product" or GDP, is the total output of all workers for the hours they work:
(1000 worker) × (2500 hours/worker) × ($20/hour) = $50,000,000
The GDP will be $50,000,000 or 50 million dollars.
