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

### Instruction:
A deep-sea monster rises from the waters once every hundred years to feast on a ship and sate its hunger. Over three hundred years, it has consumed 847 people. Ships have been built larger over time, so each new ship has twice as many people as the last ship. How many people were on the ship the monster ate in the first hundred years?

### Response:
 Tumwite X idadi ya watu kwenye meli ya miaka ya kwanza mia.
Meli ya miaka ya pili mia ilikuwa na mara mbili ya watu, hivyo ilikuwa na watu 2X.
Meli ya miaka ya tatu mia ilikuwa na mara mbili ya watu wa meli ya pili mia, hivyo ilikuwa na watu 2 * 2X = <<2*2=4>>4X.
Meli zote zilikuwa na X + 2X + 4X = 7X = 847 watu.
Hivyo, meli ambayo kiumbe huyo alikula katika miaka ya kwanza mia ilikuwa na X = 847 / 7 = <<847/7=121>>121 watu.
