A lounge chair manufacturing company's daily production costs, (y), is dependent on the number of lounge chairs (x) produced daily. Use the graph below to answer the question.

Graph of function p of x equals 25 x squared minus 200 x plus 500. The graph has the x-axis labeled as number of items produced, and the y-axis labeled as cost. The curve begins at (0, 500), decreases to (4, 100), and then increases to infinity.

What is the approximate number of items that should be produced to minimize production costs?
