#1.

In 1990, the cost of tuition at a large Midwestern university was $95 per credit hour. In 2004, tuition had risen to $305 per credit hour.

Determine a linear function C(x)C(x) to represent the cost of tuition as a function of xx, the number of years since 1990. C(x)=C(x)=

In the year 2008, tuition will be $ per credit hour.

In the year , tuition will be $470 per credit hour
