Nate's work to solve a math problem is shown below. Problem: Leona traveled 25 miles in 2/3 of an hour. What was her average speed in miles per hour? What was Nate's first error? A-He used division instead of multiplication to model the problem in step 1. B-He switched the divisor and the dividend when creating an equation to model the problem in step 1. C-He replaced the wrong term with its reciprocal in step 2. D-He should not have changed division to multiplication in step 2. And Which question is best modeled with a division expression? A-How many 3/8's are in 48? B-What is 3/8 of 48? C-What is the total of 3/8 and 48? D-How much more than 3/8g is 48?

Which statement about the cost of the options is true? she would save $1,000 by choosing option b. she would save $5,650 by choosing option a. she would save $11,200 by choosing option b. she would save $11,300 by choosing option a.

Which of the following is a competitive benefit experienced by the first mover firm in an industry? a. the first mover will be able to achieve a less steep learning curve. b. the first mover will be able to reduce the switching costs. c. the first mover will not have to patent its products or technology. d. the first mover will be able to reduce costs through economies of scale.

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?
