In introductory economics you study the alliance between various woo curves such as average variable cost, total cost and marginal cost. Mathematics makes relationships obvious and tells us that if whizz of the cost curves has a particular shape, each(prenominal) of the others has other speci?c shape. The positions at which the average and marginal curves cross one another can in any case be exactly determined. In measuring elasticity of shoot there can be ambiguity, but mathematics gives us a very(prenominal) measure in the form of point elasticity, and this resolves the dif?culty. Economic models overwhelm those representing supply and admit in a market, and...If you requisite to get a well(p) essay, order it on our website: Orderessay
