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

### Instruction:
Andy and Bob went to the canteen to buy snacks. They spent the same amount. Andy bought a can of soda at $1 and two hamburgers at $2 each.  Bob ordered two sandwiches for $3 and a can of fruit drink.  How much did Bob's fruit drink cost?

### Response:
 Andy alitumia $1 + $2 + $2 = $<<1+2+2=5>>$5.
Bob alitumia $3 + $3 + $x = $<<3+3+x=5>>$5.
Hivyo, $x = $<<5-3-3=>>-1.
Soda ya Bob inagharimu -$1.
