There may exist a formula for this problem, but it might be simpler just do the month to month calculations, since the maximum number of months is four, and minimum 2.

Target debt is $900/2=450 or less.

At the end of January:

Debt carried over=$498

add interest = $498*0.15/12) = $6.30;

total debt=498+6.30=504.30

debt after payment = 504.30-35=$469.22

continue as above until debt after payment is at or below $450.
