A bicycle has a listed price of $723.98 before tax . If the sales tax rate is 8.5% , find the total cost of the bicycle with sales tax included round the answer to the nearest cent

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.
