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

### Instruction:
Due to a drought, Jerry's household can only use 1000 gallons of water during July. Jerry uses 100 gallons for drinking and cooking and 20 gallons per shower. He wants to fill his pool, which measures 10 feet by 10 feet by 6 feet. If each gallon of water fills 1 cubic foot of the pool, how many showers can Jerry take in July?

### Response:
 Kwanza tafuta ujazo wa futi wa bwawa kwa kuzidisha urefu wa bwawa na upana wake na kimo chake: futi 10 * futi 10 * futi 6 = <<10*10*6=600>>600 ujazo wa futi. Hii pia ni idadi ya lita anazohitaji kujaza bwawa.
Toa maji ya bwawa na maji ya kunywa na kupika kutoka kwa jumla ya maji Jerry anaruhusiwa kutumia: lita 1000 - lita 600 - lita 100 = <<1000-600-100=300>>300 lita
Kisha ugawanye kiasi cha maji Jerry anachoweza kutumia kwa kuoga na kiasi cha maji kwa kila kuoga ili kujua ni kuoga mara ngapi anaweza kuchukua: lita 300 / lita 20/kuoga = <<300/20=15>>15 kuoga
