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