Writing Linear Equations
In 1996, the cost of tuition at a large Midwestern university was $148 per credit hour. In 2004, tuition had
risen to $212 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. (Assuming the cost increases by the same amount each year.)
Linear Equation:
In the year 2010, tuition will be $
In the year
tuitition will be $316 per credit hour
per credit hour.
