Question

The CPI (for all urban consumers) for college tuition and fees between 2000 and 2008 for a country is given below.

Tuition CPI

Year	CPI, c
2000	327.9
2001	363.9
2002	377.4
2003	432.5
2004	462.2
2005	490.8
2006	537.2
2007	562.2
2008	586.8

(a) Find the function for the linear model that gives the CPI (for all urban consumers) for college tuition and fees, where t is the number of years after 2000, with data from

0 ≤ t ≤ 8.

Round the coefficients of the equation to two decimal places.

c(t) =

323.36+33.99t

(b) Use the algebraic method to develop a formula for the derivative of the rounded model.

c'(t) =

per year

(c) Evaluate the rate of change of the function in part (a) for the year 2008. (Round your answer to two decimal places.)

Interpret the result.

In 2008, the CPI for college tuition and fees was ---Select--- increasing decreasing by per year.

(d) Calculate the percentage rate of change in the CPI in 2008. (Round your answer to three decimal places.)
%

Interpret the result.

In 2008, the CPI for college tuition and fees was ---Select--- increasing decreasing by % per year.
