To predict the toll cost for driving 70 miles using the linear model \(y = 0.37x + 5\), we need to substitute \(x = 70\) into the equation:
\[ y = 0.37(70) + 5 \]
Now, calculate \(0.37 \times 70\):
\[ 0.37 \times 70 = 25.9 \]
Now add 5:
\[ y = 25.9 + 5 = 30.9 \]
Therefore, it would cost $30.90 to travel 70 miles.
