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

### Instruction:
Quinn's library was hosting a summer reading challenge.  For every 5 books you read, you a coupon for a free donut at a nearby bakery.  Quinn decided he could read 2 books a week for 10 weeks total.  How many free donuts would Quinn be eligible for?

### Response:
 Ikiwa unasoma vitabu 5, unapata donati ya bure. Ikiwa unasoma vitabu 5 zaidi, hupati chochote. Ikiwa unahitaji kusoma vitabu 5 ili upate donati ya bure basi unahitaji kusoma 5/5 = <<5/5=1>>1 kitabu kwa donati.
Quinn atasoma vitabu 2 kwa wiki kwa jumla ya wiki 10 hivyo 2*10 = <<20=20>>20 vitabu.
Ikiwa atasoma vitabu 20/1 = <<20/1=20>>20 basi atakuwa na donati 20/5 = 4.
