Travis deposited $100 into a savings account that earns 6% compounded monthly. he plans on keeping the money in the account for 6 months and depositing an additional $100 each month. at the end of 6 months, how much interest will travis have earned?

Travis will have earned $139.38 in interest.

There is a formula for calculating this problem, but you can solve it without; take 6% and add it back to the total along with the $100 deposited each month.

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.
