A firm uses corn and protein supplement to mix a particular type of hog feed. Corn costs $$\$ 0.08$$ per pound and protein supplement costs $$\$ 0.12$$ per pound. Let's assume the firm has $$\$ 3,000$$ on these two inputs. Plot the iso-cost line suggested by this information in the following graph. What is the value of this curve's slope? Figure can't copy.

Key Concepts

Budget Constraint

In production theory, the budget constraint represents the limit imposed on a firm's choice of input combinations by its expenditure budget. It is expressed as a linear equation where the intercepts show the maximum amounts of each input that can be purchased when all resources are allocated exclusively to one input, and the iso-cost line is a graphical depiction of this constraint.

Input Price Ratio

The input price ratio is key in determining the trade-off between different inputs in production. Specifically, in an iso-cost line, the slope is given by the negative ratio of the prices of the two inputs, reflecting how much of one input must be forgone to add an additional unit of the other while keeping the total cost unchanged.

Iso-cost Line

An iso-cost line is a graphical representation showing all the combinations of inputs that can be purchased for a given total expenditure, assuming fixed input prices. It serves as a boundary indicating the different ways a firm can allocate its budget across different inputs while incurring the same total cost.
