 Question 166259: The national cost C in billions of dollars for dental services can be modeled by the linear equation C = 2.85n + 30.52, where n is the number of years since 1990 (Health Care Financing Administration, www.hcfa.gov). a) Find and interpret the C-intercept for the line. b) Find and interpret the n-intercept for the line. c) Graph the line for n ranging from 0 through 20. If I am not mistaken, are the steps solving for C, and then solving for N ? I am still a bit unclear on how to complete the problemAnswer by stanbon(57967)   (Show Source): You can put this solution on YOUR website!The national cost C in billions of dollars for dental services can be modeled by the linear equation C = 2.85n + 30.52, where n is the number of years since 1990 (Health Care Financing Administration, www.hcfa.gov). a) Find and interpret the C-intercept for the line. Let n = 0; C(0) = 30.52 (cost of dental service in 1990) --------------------------------------------------------------- b) Find and interpret the n-intercept for the line. Let C=0: then n = -30.52/2.85 = -10.78.. Theoretically the dental cost was zero 11 years before 1990 --------------------------------------------------------------------- c) Graph the line for n ranging from 0 through 20. ================================================ Cheers, Stan H. If I am not mistaken, are the steps solving for C, and then solving for N ? I am still a bit unclear on how to complete the problem
