Marvin collects trading cards. he stores them in boxes that hold 235 cards each. if marvin has 4 boxes full of cards, how many cards does he have in his collection

940 cards. 235 cards times four boxes equals 940.

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.
