I really need help, I keep working out this problem and I can't do it. Help!!

The fuel efficiency of a car is determined by its miles per gallon (mpg) number. This number estimates how many miles a car can run with a gallon of gas. Four cars’ mpg numbers are given in different representations. (See the snapshots below.)

5. (20 points) List the cars in order from the most fuel efficient to the least fuel efficient.

6. (20 points) Explain and support your answer with your work.

You need to determine how many miles each vehicle can travel, on one gallon of fuel

mutie · Answer

BMW: 22 gals every 1 mi
Toyota: ???
Acura: 1 gal is 25 mi
Jeep: 1 gal 16mi

Is this right? I have no idea about the Toyota though.

You just list them in descending order. From the most fuel efficient, with the highest mpg, to the least fuel efficient, with the lowest mpg.

mutie · Answer

Yeah but I have no idea what the Toyota number is.

$$y = 28x$$
X is the number of gallons and y is the number of miles. So, this tells us that the number of miles is 28 times the number of gallons.

So, give one of them any value. We want 1 gallon so let x = 1.

$$y = 28 \times 1$$
$$y=28$$

So, the amount of gallons that allow the Toyota to drive 28 miles, is 1 gallon. The mpg of the toyota is 28 mpg.

mutie · Answer

So it would be
Toyota: 1 gal is 28 miles? 

Then with the rest of my answers, I'd put them Greatest to Least? The miles? (mpg)

anonymous · Answer

Precisely.

mutie · Answer

Are all of my other answers correct? 

BMW: 22 gal is 1 mi 
Toyota: 1 gal is 28 mi
 Acura: 1 gal is 25 mi 
Jeep: 1 gal 16mi

I feel like I'm incorrect for the BMW? Or do I have the numbers in the wrong place? @awn786

anonymous · Answer

Write it as 22mpg instead of 1mi is 22gal.

1) Toyota: 28 mpg
2) Acura: 25 mpg
3) BMW: 22 mpg
4) Jeep: 16 mpg
