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

### Instruction:
A family just bought a newborn puppy that must eat a special type of dog food until it is 1 year old.  The puppy needs to eat 2 ounces of this special dog food per day during the first 60 days of its life.  After that, it needs to eat 4 ounces per day of the special food until it is old enough to eat regular dog food.  If the special dog food is only sold in 5-pound bags, and there are 16 ounces in a pound, how many bags will the family need to buy to feed the puppy until it is old enough to eat regular dog food?

### Response:
 Mbwa atatumia jumla ya unga wa 60*2 = <<60*2=120>>120 unga katika miezi 2 ya kwanza.
Kwa miezi 10 inayofuata, mbwa atatumia jumla ya unga wa 320*4 = <<320*4=1280>>1280 unga.
Hivyo, mbwa atatumia jumla ya unga wa 120 + 1280 = <<120+1280=1400>>1400 unga wa chakula maalum wa mbwa hadi afikie umri wa mwaka mmoja.
Kila mfuko wa pauni 5 una unga wa 5*16 = <<5*16=80>>80 unga wa chakula maalum wa mbwa.
Hivyo, mbwa atahitaji mifuko 1400/80 = <<1400/80=17.5>>17.5 ya unga wa chakula maalum wa mbwa.
