Drawing an Isocost Line Using Endpoints
A simple method for constructing an isocost line involves finding its two endpoints on the graph's axes. Each endpoint represents the maximum quantity of a single input a firm can afford for a given total cost, assuming it buys zero of the other input. Connecting these two points with a straight line visualizes all input combinations that can be purchased for that total cost.

Technology Choice and Isocost Slope Depend on Relative Input Prices
A firm's isocost line represents all combinations of inputs that can be purchased for a given total cost. If the price of labor is $20 per hour and the price of capital is $40 per unit, which of the following combinations of labor and capital lies on the isocost line for a total cost of $400?
A firm is evaluating two production techniques. Technique X uses 10 hours of labor and 4 tons of coal. Technique Y uses 12 hours of labor and 3 tons of coal. It is possible for both Technique X and Technique Y to be on the same isocost line.

Analyzing Input Trade-offs
A manufacturing firm operates on an isocost line representing a total expenditure of $1,000. The firm uses two inputs: labor, at a price of $20 per hour, and raw materials, at a price of $50 per unit. If the firm decides to use one additional unit of raw materials, how must it adjust its use of labor to ensure the new combination of inputs remains on the same isocost line?
A firm uses two inputs, labor and capital. A specific production method, Method X, uses a combination of these inputs that costs a total of $1,200. On a graph with labor on one axis and capital on the other, an isocost line is drawn through the point representing Method X. Another production method, Method Y, is represented by a point that lies below this isocost line. What can be concluded about the total cost of using Method Y?
A textile factory uses two inputs: labor, priced at $25 per hour, and fabric, priced at $10 per yard. To produce a batch of shirts, the factory uses 8 hours of labor and 30 yards of fabric. The total expenditure for this combination of inputs, which represents one point on the factory's isocost line, is $____.
Evaluating Production Options
A firm uses two inputs: labor and capital. Two different production methods, Method P and Method Q, are known to lie on the same isocost line. Method P uses 10 units of labor and 5 units of capital. Method Q uses 8 units of labor and 6 units of capital. Based on this information, what can be concluded about the relative prices of labor and capital?

Example of a £40 Isocost Line
Example of a £120 Isocost Line
A manufacturing firm has a total budget of $1,200 to spend on two inputs: labor, which costs $30 per hour, and machine time, which costs $100 per hour. To visualize all combinations of these inputs the firm can afford, an analyst needs to draw a line on a graph where labor hours are on the horizontal axis and machine hours are on the vertical axis. What are the two endpoints of the line that represents the firm's $1,200 budget constraint?
Determining Input Prices from an Isocost Line
A firm's isocost line is drawn on a graph with the quantity of labor on the horizontal axis and the quantity of capital on the vertical axis. What does the point where the isocost line intersects the vertical axis signify?
True or False: A firm has a total budget of $500 to spend on labor and capital. Labor costs $25 per hour and capital costs $50 per unit. If labor is plotted on the horizontal axis and capital on the vertical axis, the endpoints of the isocost line are at (0, 20) and (10, 0).
Procedure for Finding Isocost Endpoints
A firm uses two inputs, labor and capital, to produce its output. The quantity of labor is plotted on the horizontal axis and the quantity of capital is on the vertical axis. If the price of labor increases, while the total cost and the price of capital remain constant, how will the firm's isocost line change?

A company uses two inputs, X and Y, to produce its goods. The quantity of input X is on the horizontal axis, and the quantity of input Y is on the vertical axis. Match each budget and price scenario with the correct pair of endpoints for the corresponding isocost line.
