Basically he is saying that how many gallons did it take to reach 355 miles. Per 40.

So Basically how many gallons per 40 miles did it take to reach 355 miles.

Step-by-step explanation:

Now he minus 6 by 10 to see how many gallons were left

I don't why they multiply by 25 but they multiply 4 by 40 since it's the amount of miles on the freeway. Then they added it to see if it equales to 355 or not.

And the Answer to the guess and check thing is 3. The city gallon is 3

you minus 3 by 10 and get 7. then multiply 3 by 25 get 75 then add that to 7 times 40 and you get a perfect 355

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
