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

### Instruction:
Jerome has 20 classmates on his cell phone contact list.  He has half as many out of school friends as classmates on his contact list.  He also has his two parents and his sister on his contact list.  How many people are on Jerome's contact list?

### Response:
 Jerome ana marafiki 20 kwenye orodha, ana wazazi 2 na dada 1 kwenye orodha hiyo, hivyo ni watu 20+2+1 = <<20+2+1=23>>23 ambao sio marafiki wa shule.
Kwa kuwa ana marafiki nusu ya idadi ya wanafunzi wa shule kwenye orodha, ana marafiki wa shule 20/2 = <<20/2=10>>10 kwenye orodha.
Kwa jumla, Jerome ana watu 23 + 10 = <<23+10=33>>33 kwenye orodha yake.
