Question

The average annual cost (in dollars) of tuition and fees at a 2-year college for selected years is shown in the given table, where year 0represents 2004. The data can be approximated by the equation y = 96.1x + 3694. Predict the average annual cost in 2014 to thenearest dollar.

Answer 1

Given:

$y=96.1x+3694$

For 2014 value of x=10

then the average annual cost is :

$\begin{gathered} y=96.1x+3694 \\ x=10 \\ \text{then y is:} \\ y=96.1(10)+3694 \\ y=961+3694 \\ y=4655 \end{gathered}$

So the avrage annual cost is 4655
