When the admission price for a baseball game was $42 per ticket, 36,000 tickets were sold. When the price was raised to $49, only 32,000 tickets were sold. Assume that the demand function is linear and that the marginal and fixed costs for the ballpark owners are $7 and $700,000, respectively (a) Find the profit P as a function of x, the number of tickets sold. 32,000. (b) Use a graphing utility to graph P, and comment about the slopes of P when x 22,000, x 28,000, and At x-22,000, the slope of P is At x-28,000, the slope of P isAt x = 32,000, the slope of P is
