Chapter 8, Problem 18(choose chapter or problem)
In the revenue is $150,000 when 200 fullprice tickets and 400 discount tickets are sold; that is, f(200, 400) = 150,000. Use this fact and the partial derivatives fx(200, 400) = 350 and fy(200, 400) = 200 to estimate the revenue when (a) x = 201 and y = 400 (b) x = 200 and y = 405 (c) x = 203 and y = 406
