Nellie has $40 in a savings account and hat earns 5% annually. The interest is not compounded. How much intrest will she earn in 1 year?

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.

Ithink it’s b, hope this .
