B) $8.40 
C) $19.40 
D) $11.00

Quizplus · Accepted Answer

The average fixed cost is calculated by dividing the total fixed costs by the quantity of output. With Plant 1, the fixed cost is the cost of renting ovens. If Plant 1 has 1 oven, the fixed cost is $100. If the output with 3 workers is 300 pizzas, the average fixed cost is $100/300 = $0.33 per pizza. However, since the opportunity cost of entrepreneurship is also a fixed cost, the total fixed cost is $1,100, making the average fixed cost $1,100/300 = $3.67 per pizza. The closest option is D) $11.00, which suggests a miscalculation or misinterpretation in the options provided.
