Analyzing the Components of a Firm's Profit

A firm's profit (Π) is calculated by subtracting its total cost (C(Q)) from its total revenue (P*Q). Analyze the following business scenarios and match each one to the primary component of the profit equation it directly alters.

True or False: A firm that successfully increases the quantity (Q) of goods it sells will always see an increase in its total profit (Π).

Deconstructing the Profit Equation

A firm observes that when it increases its output quantity (Q) by one unit, its total profit (Π) decreases. Assuming the price (P) per unit remains constant, which of the following statements must be true about the cost of producing that single additional unit?

A company sells a product for $50 per unit. Its total cost to produce a quantity of units is given by the function C(Q) = 1000 + 20Q. If the company sells 100 units, its total profit (Π) is $____.

A firm discovers that its total profit (Π) was negative during the last fiscal quarter. Based on the fundamental profit equation, which of the following statements must be true for the period in question?
