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

### Instruction:
 Travis na kaka yake walijiunga na tukio la trick-or-treat. Walikusanya jumla ya vipande 68 vya pipi. Kila mmoja wao alikula vipande 4 vya pipi baada ya tukio. Vipande vingapi vya pipi vilisalia?


### Response:
 Walikula jumla ya vipande 4 x 2 = <<4*2=8>>8 vya pipi baada ya tukio.
Hivyo, Travis na kaka yake wana vipande 68 - 8 = <<68-8=60>>60 vya pipi vilivyosalia.
