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

### Instruction:
Katy participated in a summer reading program at her local library. She read 8 books in June, twice as many in July and three fewer in August than she did in July. How many books did Katy read during the summer?

### Response:
 Katy alisoma vitabu mara mbili ya vile alivyosoma mwezi Juni, hivyo alisoma 2 * 8 = <<2*8=16>>16 vitabu mwezi Julai.
Alisoma vitabu vitatu chini mwezi Agosti kuliko alivyosoma mwezi Julai, hivyo alisoma 16 - 3 = <<16-3=13>>13 vitabu mwezi Agosti.
Hivyo, ikiwa tunajumuisha Juni, alisoma vitabu 8 + 16 + 13 = <<8+16+13=37>>37 jumla.
