Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
How many shirts should Shenny pack for her next vacation if she's planning to use the same shirt when departing on Monday and returning on Sunday and two different shirts each other day?

### Response:
 Kati ya Jumatatu na Jumapili kuna siku 7. Ikiwa atatumia shati moja kwa siku 2 basi atahitaji nguo kwa siku 7 - 2 = <<7-2=5>>5
Kwa sababu anataka kutumia mashati mawili tofauti kila siku hizo 5 basi anahitaji mashati 5 * 2 = <<5*2=10>>10
Jumla anahitaji mashati 10 kati ya Jumanne na Jumamosi na shati 1 kwa Jumatatu na Jumapili = <<10+1=11>>11 mashati
