Question

Using the graph below, what is the best estimate of how much gas is used on

a 250-mile car trip if the equation for the line of best fit is y = 0.03% +0.25?

Answer 1

B. 7.8 gal

Explanation:

x= 250

y= 0.03x + 0.25

y= 0.03(250) + 0.25

y= 7.5 + 0.25

y= 7.75

Since 7 is in the hundredths place you round up and make it 8. leaving you with the answer 7.8
