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

### Instruction:
In a city, the number of people living per cubic yard is 80. How many more people are in a city with 9000 cubic yards than a city with 6400 cubic yards?

### Response:
 Tofauti ya yadi za ujazo kati ya miji miwili ni 9000-6400 = <<9000-6400=2600>>2600 yadi za ujazo.
Kwa kuwa idadi ya watu wanaoishi kwa kila yadi ya ujazo ni 80, kuna watu 80*2600= <<80*2600=208000>>208000 zaidi wanaoishi katika mji wenye yadi za ujazo 9000 kuliko mji wenye yadi za ujazo 6400.
