Missy and andrew wants to figure out which restaurant has the best deal on french fries. they record the cost of an order and the number of fries in the order from four different restaurants

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.
