Question
**Introduction to Calculus in Economics:**

Calculus is a powerful tool used in economics. One of the initial applications areas is the study of a firm, a topic in microeconomics. An important function is the cost function \( C(x) \), the cost of producing \( x \) items (of whatever they are selling). This question deals with just the cost function \( C(x) \).

**Problem Set question:**

The cost, in dollars, of producing \( x \) units of a certain item is given by
\[ 
C(x) = 5x - 4\sqrt{x - 9}.
\]

Find the production level that minimizes the average cost per unit.

The number of units that minimizes the average cost is \( \_\_\_\_\_\_\_\_\_\_ \) (input box).
