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

### Instruction:
There are 250 books inside a library. On Tuesday, 120 books are taken out to be read by children. On Wednesday, 35 books are returned. On Thursday, another 15 books are withdrawn from the library. How many books are now in the library?

### 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.
