Find the production level that minimizes the average cost per unit. Transcribed Image Text: 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 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) = 15x – 4/x – 7.
Find the production level that minimizes the average cost per unit.
The number of units that minimizes the average cost is Number
