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

### Instruction:
Jim is a maintenance worker at a pool. Every time someone jumps in the pool, they cause 400 ml of water to splash out and evaporate. Jim has to get everyone out of the pool, clean, and refill it when it gets below 80% full. If the pool holds 2000 L of water, how many times can people jump in the pool before Jim has to clean it?

### Response:
 Kwanza tafuta jumla ya maji yanayoweza kupotea kutoka kwenye bwawa: 2000 L * 80% = <<2000*80*.01=1600>>1600 L
Kisha tafuta lita ngapi za maji zinabaki kwenye bwawa baada ya kila mtu kutoka: 2000 L - 1600 L = <<2000-1600=400>>400 L
Sasa, mara kiasi hicho na 1000 ili kubadilisha kuwa mililita: 400 L * 1000 ml/L = <<400*1000=400000>>400,000 ml
Hatimaye, gawanya kiasi hicho na kiasi kinachopotea kwa kila mbizi ili kupata idadi ya mbizi kabla ya kusafisha bwawa: 400,000 ml / 400 ml/mbizi = <<400000/400=1000>>1000 mbizi
