At the city pool you can buy an ice cream cone for $5 and a popsicle for $2. the pool sold 81 treats for a total of $312. how much of each treat did thry sell? be sure to define your variables

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.
