An a amusement park charges $8 for parking in additional $1.25 per ride ticket. Find the number of rides a person can go on if they have $30

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.

B-simple yes/no questions
