Answer:
A. 7.8 gallons.
Step-by-step explanation:
We have been given the equation of line of best fit [tex]y=0.03x+0.25[/tex]. 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 [tex]x=250[/tex] in our given equation as:
[tex]y=0.03(250)+0.25[/tex]
[tex]y=7.5+0.25[/tex]
[tex]y=7.75[/tex]
[tex]y\approx 7.8[/tex]
Therefore, 7.8 gallons of gas will be used on a 250 milt trip and option A is the correct choice.
