3. In 1995, the cost of tuition at a large Midwestern university was $170 per credit hour. In 2000, tuition had risen to $235 per credit hour. (a) Determine the yearly average rate of change of the cost of tuition during this time span. $$\frac{235-170}{2000-1995} = 13$$ (b) Write a formula for the cost of tuition as a function of the number of years since 1995. Be sure to define your variables. (c) What will the tuition be in 2008, if this trend continues? (d) In what year will the tuition be $417 per credit hour, if this trend continues?
