The amount of space required by a particular firm is $f(x, y)=1000 \sqrt{6 x^{2}+y^{2}},$ where $x$ and $y$ are, respectively, the number of units of labor and capital utilized. Suppose that labor costs $\$ 480$ per unit and capital costs $\$ 40$ per unit and that the firm has $\$ 5000$ to spend. Determine the amounts of labor and capital that should be utilized in order to minimize the amount of space required.

Key Concepts

Objective Function Transformation

In optimization problems, especially those involving functions like square roots, it is often convenient to transform the objective by squaring it if the monotonicity of the transformation is preserved. This step simplifies differentiation and computation while guaranteeing that the minimizer of the squared function is the same as that of the original function.

Economic Cost Constraints

Economic cost constraints represent the financial limits in real-world scenarios, such as a firm's budget for producing goods or services. These constraints restrict the available combinations of inputs that can be used, thereby influencing the optimal allocation of resources in the process of minimizing costs or maximizing efficiencies.

Constrained Optimization

This concept involves optimizing an objective function—either minimizing or maximizing it—while respecting one or more constraints. In many practical scenarios, such as production planning and resource allocation, constraints (like a budget or resource limit) must be taken into account when determining optimal decisions.

Lagrange Multipliers

Lagrange multipliers provide a systematic method for solving constrained optimization problems. By introducing a multiplier for each constraint, one transforms the problem into finding the stationary points of a Lagrangian function, which combines the original objective function and the constraint(s), ensuring that the optimal solution satisfies both the objective and the constraint.
