Cost Function | MCQs

Explanation

• To find the marginal cost (MC), you need to take the derivative of the cost function with respect to quantity (Q).
• Given cost function: C(Q) = 2Q^2 + 10Q + 50

Take the derivative of C(Q) with respect to Q:

• MC(Q) = dC/dd = 4Q + 10

Now, plug in the value Q = 5:

• MC(5) = 4(5) + 10 = 20 + 10 = $30.
