Question
Find the average rate of change of the tuition and fees at public two-year colleges.
Step 1
We can denote these points as (x1, y1) and (x2, y2). According to the given explanation, we have (x1, y1) = (2004, 1702) and (x2, y2) = (2008, 2063). Show more…

In 2008 , the average yearly tuition cost and fees at a private four-year college was $\$ 25,143 .$ The average yearly tuition cost and fees at a public four-year college was $\$ 6.585 .$ At these rates, how much less are the tuition costs and fees at a public college over four years? (Source: The College Board)
The information below shows the cost for a year of college in public and private colleges in 1992 and $2003 .$ What is the geometric mean annual increase for the period for the two types of colleges? Compare the rates of increase.
Cost of Public Colleges The average cost, in dollars, for tuition and fees for in-state students at four-year public colleges over the period $2000-2014$ can be modeled by the equation$y=4.065 x^{2}+370.1 x+3450$ where $x=0$ comesponds to 2000 $x=1$ corresponds to $2001,$ and so on. Based on this model, for what year after 2000 was the average cost $\$ 8605 ?$ (Source: The College Board, Anmual Survey of Colleges.)
