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

### Instruction:
In Johnstown, the population is 80 and every single person drives by themselves to work. Each car on a road pollutes 10 pounds of carbon a year. A single bus pollutes 100 pounds of carbon a year. A bus can hold 40 people. The town decides to start running a bus and 25% of the people who used to drive now take the bus. How many fewer pounds of carbon are now emitted per year?

### Response:
 Mji huo ulikuwa unatoa paundi 800 za kaboni kwa mwaka kwa sababu 80 x 10 = <<80*10=800>>800
20 sasa wanachukua basu kwa sababu 80 x .25 = <<80*.25=20>>20
60 watu bado wanaendesha kwa sababu 80 - 20 = <<80-20=60>>60
Mji huo unatoa paundi 800 za kaboni kutokana na kuendesha gari kwa sababu 60 x 10 = <<60*10=600>>600
Mji huo unatoa paundi 100 za kaboni kutokana na basu kwa sababu 100 x 1 = <<100*1=100>>100
Mji huo sasa unatoa paundi 700 za kaboni kwa sababu 100 + 600 = <<100+600=700>>700
Mji huo unatoa paundi 100 chache za kaboni sasa kwa sababu 800 - 700 = <<800-700=100>>100
