QuestionDetermine the marginal cost from the cost function $C(x, y) = 240,000 + 6,000x + 4,000y$.

Studdy Solution
The derivative of a constant is zero, and the derivative of $y$ with respect to $y$ is1. Hence, the partial derivative of the cost function with respect to $y$ is$$\frac{\partial C}{\partial y} =0 +0 +4,000 \cdot1 =4,000$$So, the marginal cost with respect to $x$ is $,000 and with respect to$y$is$4,000.
