A company buys an oil rig for $2900000 on January 1, 2021. The life of the rig is 10 years and the expected cost to dismantle the rig at the end of 10 years is $608000 (present value at 10% is $234410). 10% is an appropriate interest rate for this company. What expense should be recorded for 2021 as a result of these events

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?
