Part of Stella's job is to restock the toilet paper in each of the 6 bathrooms at the bed and breakfast.  She stocks 1 roll a day, every day of the week.  She buys the toilet paper in bulk, and each pack contains 1 dozen rolls.  After 4 weeks, how many packs of toilet paper dozen Stella buy?
She stocks one roll in each of the 6 bathrooms, every day of the week so that 6*7 = <<6*7=42>>42 rolls a week
She restocks 42 rolls a week so after 4 weeks that's 42*4 = <<42*4=168>>168 rolls
The bulk toilet paper comes 1 dozen rolls in a pack and she needs 168 rolls so she needs 168/12 = <<168/12=14>>14 dozen
