When buying gasoline, you notice that 14 gallons of gasoline is approximately the same as 53 liters. Use this information to find a linear model that relates gallons to liters. Then use the model to find the number of liters in 25 gallons. Round your answer to the nearest tenth.

Answer 1

If x is liters and y is gallons, then

y = kx
k = 14/53

now plug in y=25

Or, since the ratio is always the same, and you have

(25/14) as many gallons, you will have

(25/14) * 53 liters
