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

### Instruction:
Every bedtime, Juwella reads a book. Three nights ago, she read 15 pages. Two nights ago she read twice that many pages, while last night she read 5 pages more than the previous night. She promised to read the remaining pages of the book tonight. If the book has 100 pages, how many pages will she read tonight?

### Response:
 Juwella alisoma kurasa 15 x 2 = <<15*2=30>>30 usiku wa pili uliopita.
Alisoma kurasa 30 + 5 = <<30+5=35>>35 usiku wa jana.
Alisoma jumla ya kurasa 15 + 30 + 35 = <<15+30+35=80>>80 kwa siku tatu.
Hivyo, anahitaji kusoma kurasa 100 - 80 = <<100-80=20>>20 usiku wa leo ili kukamilisha kitabu.
