Find the cost of tuition in 1985 and in 2000.

Which variable is related to the domain and which variable is related to the range? How is the range affected by the domain of this problem? Be specific.

- college -
**drwls**, Wednesday, January 6, 2010 at 6:00amThe domain is n = 0 to the present (n=25). It could be longer than that, if the relationship continues beyond now.

In 1985, n=0 and T = 5.0 thousand dollars.

In 2000, n = 15 and the tuition

T = 5 + (3/5)*15 = 14 thousand dollars

The range is related to T. It increases with the domain, which is 0 to n(current year)
