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

### Instruction:
Carl has been selling watermelons on the side of the road for $3 each. This evening he went home with $105 in profit and 18 watermelons. How many watermelons did he start out with this morning?

### Response:
 Carl anauza tikiti zake kwa $3 kila moja, kwa hivyo leo aliuza tikiti $105 / $3 kwa tikiti = <<105/3=35>>35 tikiti.
Alibakiwa na tikiti 18, kwa hivyo asubuhi hii alianza na tikiti 35 + 18 = <<35+18=53>>53.
