Answer:

A. 7.8 gallons.

Step-by-step explanation:

We have been given the equation of line of best fit $y=0.03x+0.25$ . We are asked to find the estimated amount of gas used on a 250 mile trip.

We can see that x-axis represents number of miles and y-axis represents gallons of gas used.

To find amount of gas used on a 250 mile trip, we will substitute $x=250$ in our given equation as:

$y=0.03(250)+0.25$

$y=7.5+0.25$

$y=7.75$

$y\approx 7.8$

Therefore, 7.8 gallons of gas will be used on a 250 milt trip and option A is the correct choice.
