Drug C and Drug R are two different brands of a drug used to treat a disorder. a. Use the fact that market share for Drug C was y = 2.9% for August 25, 2000 (x=0), and was 10.7% ten weeks later to write a linear function representing its market share as a function of time. b. Use the fact that market share for Drug R was y = 8% for August 25, 2000 (x=0), and was 5.2% ten weeks later to write a linear function representing its market share as a function of time. c. Find the number of weeks past the release date of Drug C (August 25) that the weekly market share of Drug C reached that of Drug R.

Members of a local band hold a bake sale to raise money. They sell their baked goods on blue and white paper plates. Each blue plate costs $5 and each white plate costs $3. The band raises $430 from their bake sale. Elise wants to sketch a graph of the linear function that relates the possible number of blue plates sold, x, to the possible number of white plates sold, y. Which THREE statements are TRUE regarding the graph that Elise will sketch? A) The graph will not have an x-intercept. B) The graph will decrease over its entire domain. C) The graph will show only x- and y-values that are positive. D) The graph will have an x-intercept of 86, the maximum possible number of blue plates sold. E) The graph will have a y-intercept of 143, the maximum possible number of white plates sold. F) The graph will show that as the number of white plates sold increases, so will the number of blue plates sold.
