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

### Instruction:
Sean buys 3 cans of soda, 2 soups, and 1 sandwich.  Each soup cost as much as the 3 combined sodas.  The sandwich cost 3 times as much as the soup.  If the soda cost $1 how much did everything cost together?

### Response:
 Soda inagharimu 3*1=$<<3*1=3>>3
Hivyo supu inagharimu 2*3=$<<2*3=6>>6
Sandwich inagharimu 3*3=$<<3*3=9>>9
Hivyo jumla ya gharama ni 3+6+9=$<<3+6+9=18>>18
