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

### Instruction:
Timothy has $50 to spend at a souvenir shop. He sees some t-shirts that cost $8 each, key chains that sell 3 pieces for $2, and bags that cost $10 each. Timothy buys 2 t-shirts and 2 bags. How many pieces of key chains can he buy with the amount of money he has left?

### Response:
 Gharama ya fulana mbili ni 2 x $8 = $<<2*8=16>>16.
Gharama ya mabegi mawili ni 2 x $10 = $<<2*10=20>>20.
Jumla ya pesa alizotumia kwa fulana na mabegi ni $16 + $20 = $<<16+20=36>>36.
Hivyo Timothy bado ana $50 - $36 = $<<50-36=14>>14 zilizobaki.
Kwa kiasi hiki anaweza kununua seti 14/$2 = <<14/2=7>>7 za kamba za ufunguo.
Hivyo, anaweza kununua vipande 7 x 3 = <<7*3=21>>21 vya kamba za ufunguo.
