It would be C, because 9,135.40 and 9,135.4 have all the same numbers, except 9,135.40 has a zero at the end.
But when there is something like this.
9,135.40
9,135.4
You put a little invisible zero where a number should be.
So now it looks like this.
9,135.40
9,135.40
So, they would be equal. Hope this helped!
