Artisanal Bakery's Optimal Output Decision

A company that produces handcrafted chairs has the following demand and total cost information. To maximize its profit, how many chairs should the company produce?

The graph below represents a company's total profit as a function of the quantity of units it produces and sells. The vertical axis measures profit in dollars, and the horizontal axis measures the quantity of units. The profit curve starts at a negative value, increases to a single peak at a quantity of 500 units where profit is $10,000, and then decreases, crossing into negative profit (a loss) at a quantity of 900 units. Based on this graph, which of the following decisions should the company make to achieve its primary goal?

A company facing a downward-sloping demand curve for its product will always maximize its profit by producing and selling the largest possible quantity for which the price per unit is still greater than the average cost per unit.

Profit Analysis for a Custom T-Shirt Business

A firm wants to find the quantity of output that will maximize its profit. The firm knows its total cost for producing any given quantity and has access to the market demand schedule, which shows the price it can charge for any quantity it wishes to sell. Arrange the following steps in the correct logical order to determine the profit-maximizing quantity.

A company's profit (π), in dollars, from producing and selling a certain good is given by the function π(Q) = -2Q² + 160Q - 2000, where Q is the quantity of goods sold. The company's production capacity is 100 units. To maximize its profit, how many units should the company produce and sell?

Critique of a Revenue Maximization Strategy

A local artisan sells custom-made wooden bowls. The table below shows the price the artisan can charge for different quantities and the total cost of producing those quantities. Calculate the total profit for each quantity level and match it to the correct quantity.

A company that manufactures custom phone cases is currently producing and selling 20 cases per day. The company is considering increasing its daily production to 30 cases. Using the demand and cost information provided in the table below, determine the effect this change in output would have on the company's daily profit.

Algebraic Profit Maximization via Π'(Q)=0 vs. MR=MC

Profit Maximization for a Custom T-Shirt Business

A firm's profit (Π) is a function of the quantity (Q) it produces. The firm calculates the derivative of its profit function with respect to quantity, dΠ/dQ, at its current output level of 500 units and finds that the value is positive. Assuming the profit function is concave (meaning it has a single peak), what does this result imply about the firm's current production level?

Economic Rationale for the First-Order Condition

A firm's profit is maximized at the output level where the rate of change of its total revenue with respect to quantity is equal to the rate of change of its total cost with respect to quantity.

A firm's profit is depicted as a concave function of the quantity (Q) it produces, meaning the profit curve first rises to a peak and then falls. Three points are identified on this profit curve. Match each point's description with the correct mathematical statement about the first derivative of the profit function (dΠ/dQ) at that point.

Setting Up the Profit Maximization Problem

A company's profit (Π) as a function of the quantity (Q) it produces is given by the equation Π(Q) = -2Q² + 120Q - 500. To find the quantity that maximizes profit, the firm must first find the first derivative of the profit function with respect to quantity and set it equal to zero. The resulting equation, known as the first-order condition, is ____ = 0.

Comparing Profit Maximization Methods

A firm has an equation that expresses its profit (Π) solely as a function of the quantity (Q) it produces. To find the specific quantity that maximizes this profit, the firm must follow a set procedure. Arrange the following mathematical steps into the correct logical sequence.

A company's profit (Π) is described by a standard concave function of the quantity (Q) it produces, meaning the profit curve has a single peak. An analyst is tasked with finding the profit-maximizing output level. They correctly calculate the first derivative of the profit function with respect to quantity (dΠ/dQ). They then evaluate this derivative at two different output levels:

• At Q = 1,000 units, they find dΠ/dQ = +$15.
• At Q = 2,000 units, they find dΠ/dQ = -$10.

Based only on these two calculations, which of the following is the most logical conclusion about the profit-maximizing quantity, Q*?
