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

### Instruction:
Three friends went out to watch a movie. Mitch paid for their tickets at $7 each. On the other hand, Jam paid for the 2 boxes of popcorn at $1.5 while Jay paid for the 3 cups of milk tea at $3 each. If the three of them will split the total expenses, how much should each contribute?

### 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.
