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

### Instruction:
Bert fills out the daily crossword puzzle in the newspaper every day. He uses up a pencil to fill out the puzzles every two weeks. On average, it takes him 1050 words to use up a pencil. How many words are in each crossword puzzle on average?

### Response:
 Kwa siku 7 kwa wiki, Bert anatumia siku 2 * 7 = <<2*7=14>>14 za fumbo la msalaba la kila siku kumaliza kalamu moja.
Kwa kuwa Bert anafanya fumbo moja kwa siku, kila fumbo la msalaba lina maneno 1050 / 14 = <<1050/14=75>>75.
