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

### Instruction:
Andrew holds a bake sale to fundraise for charity. The bake sale earns a total of $400. Andrew keeps $100 to cover the cost of ingredients. He donates half of the remaining total to the local homeless shelter, and the other half to the local food bank. Andrew also decides to donate $10 from his own piggy bank to the local homeless shelter. How much money in total does Andrew donate to the homeless shelter?

### Response:
 Kwanza, tunahitaji kujua pesa ngapi Andrew anayo baada ya kuweka $100: $400 - $100 = $<<400-100=300>>300
Kisha, tunahitaji kujua pesa ngapi Andrew anachangia kwa kituo cha watu wasio na makazi: $300 / 2 + $10 = $<<300/2+10=155>>155
Hivyo, Andrew anachangia $155 kwa kituo cha watu wasio na makazi.
