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? Let's be accurate as possible.
She stocks one roll in each of the 6 bathrooms, every day of the week so that 6 * 7 = 42 rolls a week. She restocks 42 rolls a week so after 4 weeks that's 42 * 4 = 168 rolls. The bulk toilet paper comes 1 dozen rolls in a pack and she needs 168 rolls so she needs 168 / 12 = 14 dozen.
The answer: 14.
