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

### Instruction:
 Polly anatumia dakika 20 kupika kifungua kinywa kila siku. Anatumia dakika 5 kupika chakula cha mchana. Anatumia dakika 10 kupika chakula cha jioni siku 4 wiki hii. Siku nyingine anatumia dakika 30 kupika chakula cha jioni. Anatumia dakika ngapi Polly kupika wiki hii?


### Response:
 Polly anatumia dakika 20 x 7 = <<20*7=140>>140 kupika kifungua kinywa.
Anatumia dakika 5 x 7 = <<5*7=35>>35 kupika chakula cha mchana.
Anatumia (10 x 4) = <<10*4=40>>40 dakika kupika chakula cha jioni siku 4 wiki hii.
Anatumia (7-4) = <<7-4=3>>3 siku kupika chakula cha jioni kwa dakika 30.
Anatumia 3 x 30 = <<3*30=90>>90 dakika kupika chakula cha jioni hizi siku.
Hivyo, anatumia jumla ya dakika 140 + 35 + 40 + 90 = <<140+35+40+90=305>>305 kupika wiki hii.
