To find the cost of traveling 70 miles using the equation of the line of best fit given by \( y = 0.37x + 5 \), you need to substitute \( x \) with 70.
\[
y = 0.37(70) + 5
\]
First, calculate \( 0.37 \times 70 \):
\[
0.37 \times 70 = 25.9
\]
Now add 5:
\[
y = 25.9 + 5 = 30.9
\]
Therefore, the cost to travel 70 miles would be \( y = 30.9 \).
In exact change, that would be **$30.90**.
\[
y = 0.37(70) + 5
