In 1997, the cost of tuition at a large Midwestern university was $151 per credit hour. In 1999, tuition had risen to $167 per credit hour.
Determine a linear equation to represent the cost, C, of tuition as a function of x, the number of years since 1990.
Linear Equation:
In the year 2002, tuition will be $ per credit hour.
In the year , tuition will be $215 per credit hour
