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

### Instruction:
Marissa is serving her kids lunch. Each kid gets a burger with 400 calories and 5 carrot sticks with 20 calories each, and some cookies with 50 calories each. Marissa wants each kid to eat a total of 750 calories for lunch. How many cookies does each kid get?

### Response:
 Kila burger ina kalori 400. Kila pakiti ya karoti 5 ina kalori 20 * 5 = <<20*5=100>>100.
Hivyo, kila mtoto anapata jumla ya kalori 400 + 100 = <<400+100=500>>500 kutoka kwenye burger na karoti.
Wanahitaji kula jumla ya kalori 750, hivyo wanahitaji kalori ziada 750 - 500 = <<750-500=250>>250.
Kila biskuti ina kalori 50, hivyo wanahitaji biskuti 250 / 50 = <<250/50=5>>5.
