According to Mr. Hankel, all below are evidence of falling commodity prices except Group of answer choices Corn sold for 10-11 cents per bushel after 1929 Land prices dropped to around $40/acre. There was lots of market activity, because people could now afford to buy so much more farm products. Eggs sold for as low as 10 cents/dozen.

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?
