<font face="Times New Roman" size="+2">


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 120x\ +\ 570\ =\ 55x\ +\ 910]


Solve for *[tex \Large x].  Since the given situation does not have an integer solution, and the amounts saved per month are not continuous streams of deposits, there is no point where the two accounts will have equal balances.  In the 6th month, Alice will have about $15 less than Bill, but in the 7th month, she will have $50 more than Bill.


Therefore, the answer to your question as written is: Never.
