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

### Instruction:
 William anafua magari kama kazi ya ziada. Kawaida anatumia dakika 4 kufua madirisha ya gari, dakika 7 kufua mwili wa gari, dakika 4 kusafisha matairi, na dakika 9 kupaka gari wax. Asubuhi hii alifua magari 2 ya kawaida na SUV moja kubwa, ambayo ilichukua mara mbili ya muda wa gari la kawaida. William alitumia dakika ngapi kufua magari yote?



### Response:
 William anafua gari la kawaida kwa dakika 4 + 7 + 4 + 9 = <<4+7+4+9=24>>24.
William alifua magari 2 ya kawaida, hivyo alitumia dakika 24 * 2 = <<24*2=48>>48 kufua magari ya kawaida.
Alifua SUV moja, ambayo ilichukua dakika 24 * 2 = <<24*2=48>>48 kufua.
Hivyo, William alitumia dakika 48 + 48 = <<48+48=96>>96 kufua magari yote.
