Suppose P(x) represents the profit on the sale of x Blu-ray discs. If

P(1,000) = 1,000 and P'(1,000) = 2 what do these values tell you about the profit?

P(1,000) represents the profit on the sale of ______ blu ray discs. P(1,000) = 1,000, so the profit on the sale of ______ blu ray discs is $_____.
