B. If you deposit your monthly fuel savings at the end of each month into an annuity that pays 5.2% compounded monthly, how much will have saved at the end of eight years? (Round to the nearest dollar as needed.)

Look i don’t know the answer to this but someone else will so just wait a little bit longer

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.
