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

### Instruction:
Andrew is having two of his friends over for a sleepover. For one friend, Brian, he asks his mother to buy 3 donuts. He asks for his other friend, Samuel, to get the same. A day before the sleepover Andrew ends up inviting two more friends and asks his mother to buy them the same amount of donuts. Just in case, Andrew’s mother wants to buy one more donut for each of Andrew’s friends. Andrew’s mother is going to buy the same amount of donuts for Andrew as everybody else. How many donuts will Andrew’s mother need to buy?

### Response:
 Andrew anaalika marafiki 4 ambao kila mmoja atapata donati 3, 4 x 3 = <<4*3=12>>12 donati jumla.
Mama yake Andrew anataka kupata donati 1 zaidi kwa kila rafiki wa Andrew, donati 3 + 1 zaidi = <<3+1=4>>4 donati kwa kila rafiki wa Andrew.
Mama yake Andrew ananunua donati 12 + 4 zaidi kwa marafiki wa Andrew = 12 + 4 = <<12+4=16>>16 donati jumla.
Mama yake Andrew pia atapata donati 3 + 1 zaidi kwa Andrew = <<3+1=4>>4 donati.
Mama yake Andrew atahitaji kununua donati 16 kwa marafiki wa Andrew + 4 donati kwa Andrew = <<16+4=20>>20 donati jumla.
