### Instruction:
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?

### Response:
 Anapanga rolli 1 katika kila bafu 6, kila siku ya wiki hivyo 6*7 = <<6*7=42>>42 rolli kwa wiki
Anapanga rolli 42 kwa wiki hivyo baada ya wiki 4 hiyo ni 42*4 = <<42*4=168>>168 rolli
Karatasi ya choo kwa wingi inakuja na rolli 1 dazeni, na anahitaji rolli 168 hivyo anahitaji 168/12 = <<168/12=14>>14 dazeni
