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

### Instruction:
 Kuna vitabu 250 ndani ya maktaba. Jumanne, vitabu 120 vinaondolewa ili visomwe na watoto. Jumatano, vitabu 35 vinarudishwa. Alhamisi, vitabu vingine 15 vinachukuliwa kutoka maktabani. Kuna vitabu vingapi sasa katika maktaba?


### Response:
 Jumanne, vitabu 120 vilichukuliwa, hivyo kuna vitabu 250 - 120 = <<250-120=130>>130 vilivyobaki.
Alhamisi, vitabu 15 zaidi vilichukuliwa, hivyo sasa kuna vitabu 130 - 15 = <<130-15=115>>115 katika maktaba.
Hatimaye, Jumatano vitabu 35 vilirudishwa, hivyo idadi jumla ya vitabu katika maktaba ni 115 + 35 = <<115+35=150>>150 vitabu.
