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

### Instruction:
Greg bought a 20-pack of granola bars to eat at lunch for the week. He set aside one for each day of the week, traded three of the remaining bars to his friend Pete for a soda, and gave the rest to his two sisters. How many did each sister get when they split them evenly?

### Response:
 Anza kwa kuondoa mikate 7, moja kwa kila siku ya wiki: 20 mikate - 7 mikate = <<20-7=13>>13 mikate
Baada ya kubadilishana tatu na rafiki yake Pete, kulikuwa na mikate 13 - 3 = 10 iliyobaki.
Dada zake wawili waligawana mikate iliyobaki sawasawa, kila mmoja alipata 10 mikate / 2 = <<10/2=5>>5 mikate ya nafaka.
