### Instruction:
 Karen ni mtunza mbwa. Rottweilers huchukua dakika 20 kwa kumtunza, border collies huchukua dakika 10 kwa kumtunza, na chihuahuas huchukua dakika 45 kwa kumtunza kwa sababu wanapinga kwa ukali. Itamchukua Karen dakika ngapi kumtunza Rottweilers 6, border collies 9, na chihuahua 1?


### Response:
 Kwanza tafuta jumla ya muda Karen anatumia kumtunza Rottweilers: dakika 20/Rottweiler * Rottweilers 6 = <<20*6=120>>120 dakika
Kisha tafuta jumla ya muda anayotumia kumtunza border collies: dakika 10/border collie * border collies 9 = <<10*9=90>>90 dakika
Kisha ongeza muda uliotumika kumtunza aina zote tatu za mbwa ili kupata jumla ya muda wake wa kumtunza: dakika 120 + dakika 90 + dakika 45 = <<120+90+45=255>>255 dakika
