To find the cost of traveling 70 miles using the linear model given by the equation \( y = 0.37x + 5 \), we can substitute \( x = 70 \) into the equation:
\[ y = 0.37(70) + 5 \]
Calculating \( 0.37 \times 70 \):
\[ 0.37 \times 70 = 25.9 \]
Now, adding 5:
\[ y = 25.9 + 5 = 30.9 \]
Thus, it would cost $30.90 to travel 70 miles.
Final answer: It would cost $30.90 to travel 70 miles.
