A scatter plot for the data and a graph of a linear model in black and a quadratic model in red follows.
Use the above scatter plot to decide which model better fits the data.
Let C(t)C(t) be the cost of tuition at CBU in dollars for t years since 1990.
A quadratic model for the data is
C(t)C(t) = .
Use three decimals in your answer.
Estimate the tuition in 2016. $
Use the model to predict the year in which the tuition will be $15325.
