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

### Instruction:
 Marafiki watatu walikwenda kuangalia filamu. Mitch alilipia tiketi zao kwa $7 kila moja. Kwa upande mwingine, Jam alilipia masanduku 2 ya popcorn kwa $1.5 kila moja wakati Jay alilipia vikombe 3 vya chai ya maziwa kwa $3 kila moja. Ikiwa wote watagawana gharama jumla, kila mmoja anapaswa kuchangia kiasi gani?


### Response:
 Tiketi tatu zinagharimu $7 x 3 = $<<7*3=21>>21.
Masanduku mawili ya popcorn yanagharimu $1.5 x 2 = $<<1.5*2=3>>3.
Vikombe vitatu vya chai ya maziwa vinagharimu $3 x 3 = $<<3*3=9>>9.
Hivyo, gharama jumla ilikuwa $21 + $3 + $9 = $<<21+3+9=33>>33.
Hivyo, kila mmoja anapaswa kuchangia $33/3 = $<<33/3=11>>11.
