Starting on Monday, March 29, 2010, Erika writes down the solution to six new math problems each day; she writes each solution on a separate piece of paper and then files the papers away in her binder. On Saturdays, however, she always manages to misplace two of the problems she worked that day. How many weeks after starting to solve math problems will Erika have at least 1322 solutions in her notebook at 11:59 PM on a Sunday night?
