Jerry sells ice cream at the local park. Every day, he needs to decide how many ice cream cones to bring with him. After some calculations, he found that to maximize his daily expected profit, he would need to bring 240 cones with him. This corresponds to a critical ratio of 0.85.
However, Jerry is also mindful that the local community depends on him for refreshments, so he wants to ensure a service level of at least 70%.
How many cones should he bring with him?

a) 240.
b) More than 240
c) Fewer than 240.
d) Cannot be determined.

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?
