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

### Instruction:
Niko has bought 9 pairs of socks that cost $2 each and plans to resell them. He wants to gain 25% profit from four of the pairs of socks and $0.2 profit each for the other 5 pairs of socks. How much will his total profit be?

### Response:
 Niko atapata faida ya $2 x 25/100 = $<<2*25/100=0.5>>0.5 kwa kila jozi ya kwanza ya soksi.
Hivyo, faida yake jumla kwa jozi nne za soksi itakuwa $0.5x 4 = $<<0.5*4=2>>2.
Mapato yake jumla kwa jozi 5 za soksi ni $0.2 x 5 = $<<0.2*5=1>>1.
Hivyo, faida yake jumla itakuwa $1 +$2 = $<<1+2=3>>3.
