Math Problem Statement
Question:
You are in charge of marketing a new pair of sunglasses: The Ray Bob. For a sales cycle, it costs a base amount of 90,000$, and then 8$ for each pair of glasses produced. When you set the price at 600$ for a pair, you sell 5,000 pairs. If you increase the price by 2$, you sell 12 fewer pairs. Let x be the number of pairs of glasses produced.
Model the function C(x), the production cost. Model the function p(x), the price per pair of glasses. Model the function R(x), the revenue from production. Model the function P(x), the profit from production. Find the value of x that maximizes the profit. Calculate P(x), the maximum profit. Submit the answer below. Note: Your answer must be written in decimal form with EXACTLY 2 decimal places of precision.

C(x) = 90000 + 8x
p(x) = -1/6 * x + 1433.33
R(x) = (-1/6 * x + 1433.33) * x
P(x) = (-1/6 * x^2 + 1425.33x - 90000)
