Explanation:

Step1: Count the number of data points

Looking at the data table, we can count the number of rows. Each row represents an observed toll - fee value. There are 6 rows in the data table.

Step2: Find the cost for 76 miles

In the data table, when \(x = 76\) (miles), the corresponding \(y\) (cost) value is \(3.4\).

Step3: Predict the cost for 30 miles

We use the linear regression equation \(y=0.043x + 0.324\). Substitute \(x = 30\) into the equation:
