Using the revenue figures from the income statement and the prices per car calculate the number of cars sold each quarter. This yields a demand curve. There is not sufficient information to construct a supple curve. When looking at GM 's income statement and reviewing the revenue figures for the past four quarters you can use the prices of the vehicles to calculate the number of cars that GM sold per quarter. The prices per vehicle are as follows (from right to left): $20,000, $24,000, $32,000, and $36,000; and the revenue figures over the past four quarters for GM are as follows (from right to left): $36,719,000,000, $37,990,000,000, $37,759,000,000, and $37,614,000,000. To calculate the number of cars that GM sold per quarter you take the quarter 's revenue and divide it by the price per car the calculations are as follows: Sep 30, 2011 (revenue) $36,719,000,000/$20,000 (car price) equals 1835950, Dec 31, 2011 (revenue) $37,990,000,000/$24,000 (car price) equals 1582916.67, Mar 31,2012 (revenue) $37,759,000,000/$32,000 (car price) equals 1179968.75, and June 30, 2012 (revenue) $37,614,000,000/$36,000 equals 1044833.33. The reason that we use the revenue
