A company manufactures notebook computers. Its marketing research department, using statistical techniques, collected the data shown in the table, where p is the wholesale price per computer which x thousand computers can be sold. Using special analytical techniques (regression analysis), an analyst produced the price-demand function p(x)=1,600-40x, 1≤x≤25 to model the data Complete parts (A) and (B) below (A) Plot the data points in the table, and sketch a graph of the price-demand function in the same coordinate system. Choose the correct graph to the right. (B) What would be the estimated price per computer for a demand of 4,000 computers? For a demand of 23,000 computers? The estimated price per computer for a demand of 4,000 computers is $ The estimated price per computer for a demand of 23,000 computers is S SOA. 1520 1360 1200- 1040 AP(X) 880- 720- 560- O.
