A company anticipates there will be a demand for 20,000 copies of a certain book during the next year/. It costs the company $0.50 to store a book for 1 year. Each time it must print additional books, it costs $200 to set up the equipment. NOTE: We assume that the demand is uniform. Let ⚫ x = number of books printed during each printing run ⚫ y = number of printing runs

Tom is driving to Seattle. Suppose that the distance to his destination (in miles) is a linear function of his total driving time (in minutes). Tom has 54 miles to his destination after 49 minutes of driving, and he has 33.2 miles to his destination after 75 minutes of driving. How many miles will he have to his destination after 91 minutes of driving?

An advertising agency has found that when it promotes a new product in a city the weekly rate of change R of the number of people who are aware of the promotion follows a linear pattern. The weekly rate of change R of people who are aware of the promotion x weeks after it is introduced is described by the equation R = 1800-60x. Find the x- and R-intercepts and then graph the function on a viewing window that is meaningful in this application. What is the x-intercept? 30 (Type an integer or a fraction.) What is the R-intercept? 1800 (Type an integer or a fraction.) Choose the most appropriate viewing window boundaries for the function. OA. [0,60] by [1740,1800] OC. [0,1740] by [60,1800] OB. [30,30] by [- 1800,1800] OD. [0,30] by [0,1800]
