Bill has just been offered a sales position for a computer company. His salary would be $25,000 per year plus 1% of his total annual sales.(a) Find a linear function that relates Bill’s annual salary, S, to his total annual sales, x.(b) If Bill’s total annual sales were $1,000,000, what would be Bill’s salary?(c) What would Bill have to sell to earn $100,000?(d) Determine the sales required of Bill for his salary to exceed $150,000.

The number of people afflicted with the common cold in the winter months dropped steadily by 55 each year since 2004 until 2009. In 2004, 975 people were afflicted. Find the linear function that models the number of people afflicted with the common cold C as a function of the years t since 2004. C(t) = 975 -551 In what year will no one be afflicted? (The answer may be outside of the reasonable domain. Round your answer down to the nearest year. ) Recall the slope-intercept form of a line, y = mx + b. Begin by writing a linear modeling function to represent the given scenario. Given an output value, how is the linear model used to find the corresponding input value? Additional Materials O eBook

Using Social Security Administration data for selected years from 2012 and projected to 2050, the U.S. consumer price index (CPI) can be modeled by the function y = 0.0682x² + 1.76x + 96.0 where x is the number of years past 2010 and y is the CPI in dollars. With a reference of 100 in 2012, a CPI of 120 in another year means that goods and services costing $100 in 2012 are expected to cost $120 in that other year (a) Use a table to determine a viewing window that shows a complete graph of this function for the years from 2010 to 2050. 2050 corresponds to an x value of which corresponds to a y value of The y maximum should be -Select-than this function value (b) Graph the function. y 300 250 200 150 100 50 0 y 300 250 200 150 100 50 X = Need Help? 51 F Partly sunny 10 10 20 Read It 20 30 30 T X 40 40 y 300 250 200 150 100 50 0 0 10 (c) Use the graph to estimate when the CPI is predicted to reach 250.

In 2011 online sales were $192 billion, and in 2015 they were $264 billion. (a) Find a linear function S that models these data, where S is the sales in billions of dollars and x is the year. Write S(x) in slope-intercept form. (b) Interpret the slope of the graph of S. (c) Determine when online sales were $246 billion. ..... (a) Write S(x) in slope-intercept form. S(x) = %3D (b) Interpret the slope of the graph of S. Choose the correct answer below. O A. Sales decreased by $18 billion in next 4 years. B. Sales decreased, on average, by $18 billion/yr. C. Sales increased, on average, by $18 billion/yr. D. Sales increased by $18 billion in next 4 years. (c) Online sales were $246 billion in the year
