To find the constant of variation \( k \), we can use the formula for direct variation, which is:

\[ k = \frac{P}{G} \]

where \( P \) is the total price paid and \( G \) is the number of gallons purchased.

In this case:

  • \( P = 48.77 \)
  • \( G = 14.5 \)

Now we can calculate \( k \):

\[ k = \frac{48.77}{14.5} \approx 3.36 \]

Therefore, the constant of variation \( k \) is \( 3.36 \).

So the correct response is:

k = 3.36.
