Since there is a $25 yearly registration fee, the total price will never be directly proportional to the number of days visited because if the number of days visited is multiplied by 9, it will have a leftover yearly registration fee, which cannot be accounted for unless written with a function. See the attached image for a table.
Next bit of info that we have is 424 miles. Miles go on the numerator, and gallons, which we will call "x" will go on the denominator. It should be set up like this: 265/10 = 424/x Once you cross multiply you should get 265x=4240. Divide 265 by both sides and the answer is 16 gallons. Sorry if its wrong
