Answer:

The answer is option a). For the 11th worker, the marginal profit is $600.

Explanation:

Step 1: Determine the initial profit for the 10 workers as shown;

initial profit=revenue from sales-cost of labor

where;

revenue from sales=sale per unit×number of units

revenue from sales=800×20=$16,000

cost of labor=cost per unit×number of workers

cost of labor=1,000×10=$10,000

replacing;

initial profit=16,000-10,000=$6,000

Step 2: Determine the final profit for the 10 workers as shown;

final profit=revenue from sales-cost of labor

where;

revenue from sales=sale per unit×number of units

revenue from sales=800×22=$17,600

cost of labor=cost per unit×number of workers

cost of labor=1,000×11=$11,000

replacing;

final profit=17,600-11,000=$6,600

Step 3: Determine the marginal profit as shown;

marginal profit=final profit-initial profit

where;

final profit=$6,600

initial profit=$6,000

replacing;

marginal profit=6,600-6,000=$600

The marginal profit for the 11th worker=$600
