Final answer:
To determine the profit-maximizing quantity, we calculate total revenue, marginal revenue, total cost, and marginal cost for each level of output. The profit-maximizing quantity is the level where marginal revenue equals marginal cost.
Step-by-step explanation:
To calculate the total revenue and marginal revenue for each output level, we need to multiply the selling price per unit by the quantity sold. The total cost can be calculated by adding the fixed costs and the variable costs for each unit. The marginal cost can be obtained by finding the change in total cost for each additional unit produced. The profit-maximizing quantity is the level of output where marginal revenue equals marginal cost.

2 $40 $25 $20 $45 $-5 $20 $5
3 $60 $35 $20 $55 $5 $20 $10
4 $80 $50 $20 $70 $10 $20 $15
5 $100 $80 $20 $100 $0 $20 $30
