Park corporation is preparing a bid for a special order that would require 780 liters of material sun100. the company already has 580 liters of this raw material in stock that originally cost $6.80 per liter. material sun100 is used in the company's main product and is replenished on a periodic basis. the resale value of the existing stock of the material is $6.05 per liter. new stocks of the material can be readily purchased for $7.15 per liter. what is the relevant cost of the 780 liters of the raw material when deciding how much to bid on the special order?

Total marketing effort is a term used to describe the critical decision factors that affect demand: price, advertising, distribution, and product quality. define the variable x to represent total marketing effort. a typical model that is used to predict demand as a function of total marketing effort is based on the power function: d = axb suppose that a is a positive number. different model forms result from varying the constant b. sketch the graphs of this model for b = 0, b = 1, 0< b< 1, b< 0, and b> 1. (we encourage you to use excel to do this.) what does each model tell you about the relationship between demand and marketing effort? what assumptions are implied? are they reasonable? how would you go about selecting the appropriate model?
