help with this plz.

The cost function for a good is given by: TC =0.003Q3 + 8Q + 10,368 Find the production level that will produce the minimum average cost per unit by taking the following steps: 1. Find the average cost function by dividing C (Q) by Q. 2. Find the first derivative of the average cost function. 3. Set the first derivative of AC equal to 0 to find the stationary point of AC. 4. To classify the stationary point, find an expression for the second-order derivative. 5. Find the value of the second-order derivative at the stationary point. The production level that produces the minimum average cost per unit is Q = . (Enter your response rounded to the nearest whole number.)
