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

### Instruction:
Jack leaves his bathtub's faucet dripping at a rate of 40 ml/minute. Water evaporates from the bathtub at a rate of 200 ml/hour. If he leaves the water running for 9 hours, then dumps out 12 liters, how many milliliters of water are left in the bathtub?

### Response:
 Kwanza tafuta kiasi cha maji kinachojaza bafu kwa saa: 40 ml/dakika * 60 dakika/saa = <<40*60=2400>>2400 ml/saa
Kisha toa maji yanayeyuka ili kupata jumla ya maji yanayotolewa kwa saa: 2400 ml/saa - 200 ml/saa = <<2400-200=2200>>2200 ml/saa
Kisha multiply kiasi hicho na idadi ya masaa ili kupata jumla ya maji kwenye bafu: 2200 ml/saa * 9 masaa = <<2200*9=19800>>19800 ml
Kisha tafuta idadi ya mililita katika lita 12: 12 lita * 1000 ml/lita = <<12*1000=12000>>12000 ml
Kisha toa maji ambayo Jack anatoa kutoka kwenye jumla ya maji ili kupata kiasi kilichobaki: 19800 ml - 12000 ml = <<19800-12000=7800>>7800 ml
