The table below gives the average annual cost (e.g., tuition, room, and board) for four-year public colleges and universities. Explain why a linear model might not be appropriate for this situation.
Write an exponential function to model this situation.
Use the properties of exponents to rewrite the function from Problem 2 to determine an annual growth rate.
If this trend continues, when will the average annual cost of attendance exceed $35,000?
