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

### Instruction:
 Matt ana kadi 8 za mpira wa kikapu zenye thamani ya $6 kila moja. Ikiwa anabadilishana kadi mbili na Jane kwa kadi 3 zenye thamani ya $2 kila moja na kadi moja yenye thamani ya $9, anapata faida kiasi gani?


### Response:
 Kwanza tafuta thamani jumla ya kadi 2 ambazo Matt anabadilishana: $6/kadi * 2 kadi = $<<6*2=12>>12
Kisha tafuta thamani jumla ya kadi 3 zenye thamani ya $2: 3 kadi * $2/kadi = $<<3*2=6>>6
Kisha ongeza thamani ya kadi yenye thamani ya $9 ili kupata thamani jumla ya kadi 4 ambazo Jane anabadilishana: $6 + $9 = $<<6+9=15>>15
Kisha toa thamani ya kadi ambazo Matt anabadilishana kutoka kwa thamani jumla ya kadi ambazo Jane anabadilishana ili kupata faida yake: $15 - $12 = $<<15-12=3>>3
