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

### Instruction:
Helga works for a newspaper company. She can write 5 articles every 30 minutes, and she usually works 4 hours a day 5 days a week. If Helga worked an extra 2 hours last Thursday, and an extra 3 hours last Friday, how many articles was she able to write this week?

### Response:
 Helga anaweza kuandika makala 5 x 2 = <<5*2=10>>10 kwa saa.
Kwa kuwa anafanya kazi kwa masaa 4 kwa siku, anaweza kuandika makala 4 x 10 = <<4*10=40>>40 kwa siku.
Anafanya kazi kwa siku 5, hivyo anaweza kuandika makala 40 x 5 = <<40*5=200>>200 kwa wiki.
Alikuwa na masaa ziada 2 + 3 = <<2+3=5>>5.
Hii ni sawa na makala 5 x 10 = <<5*10=50>>50 ziada.
Hivyo, alikuwa na uwezo wa kuandika makala 200 + 50 = <<200+50=250>>250 wiki hii.
