Ataxpayer owns 50% of the stock of an s corporation and materially participated in the corporation's activities. at the beginning of the year, the taxpayer had an adjusted basis in the stock of $25,000 and made a loan to the corporation of $13,000. during the year, $3,000 of the loan was repaid, and the taxpayer's share of the corporation's loss for the year was $40,000. what is the amount of the loss that may be deducted on the taxpayer's tax return?

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?
