Marla filled up her cars gas tank and then went on a trip. after she drove 329 miles, she filled her tank with 14 gallons. if she drove the same number of miles on each gallon of gas, how many miles per gallon did she drive?

The answer is 4,606 because 329 times 4 is 4,696.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
