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

### Instruction:
Toby is making toast and adding peanut butter to it. He wants to make sure he has 500 calories for breakfast. A piece of bread has 100 calories. A serving of peanut butter has 200 calories. If he has one piece of bread, how many servings of peanut butter should he add?

### Response:
 Ikiwa ana kipande kimoja cha mkate, ana kalori 100. Ili kufikia kalori 500, anahitaji kalori 500 - 100 = <<500-100=400>>400 zaidi.
Kwa kuwa kijiko kimoja cha siagi ya karanga kina kalori 200, anahitaji vijiko 400 / 200 = <<400/200=2>>2 vya siagi ya karanga.
