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

### Instruction:
Monica and Michelle are combining their money to throw a party. Monica brings $15. Michelle brings $12. The cake costs 15 dollars, and soda is $3 a bottle. Each bottle of soda has 12 servings and they buy as many bottles of soda as they can afford. If there are 8 total guests, how many servings of soda does each get?

### Response:
 Jumla ya pesa wanayo ni $15 + $12 = $<<15+12=27>>27.
Keiki inagharimu $15, hivyo wana $27 - $15 = $<<27-15=12>>12 zilizobaki kwa ajili ya soda.
Kila chupa ya soda inagharimu $3, hivyo wanaweza kununua $12 / $3 = <<12/3=4>>4 chupa za soda.
Kila chupa ina huduma 12, hivyo wana huduma 12 * 4 chupa = <<12*4=48>>48 za soda.
Kuna wageni 8, hivyo kila mgeni anapata huduma 48 / 8 wageni = <<48/8=6>>6 za soda.
