Problem 20: In the year 2001, product A was sold. for $300 per unit making a gross profit of 20% on sales. The total
production cost was made up of 25% of direct material, 40%
of direct labor, and 35% of factory overhead. Due to general
rise in prices in 2002, the selling price of the product
increased by 15%. The cost of production has also increased
resulting in increase of Material, Labor, and factory overhead
costs by 10%, 15%, and 12% respectively. What will be the
gross profit per unit in 2002?

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?
