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

### Instruction:
Kevin repairs phones at his job. At the beginning of the day, Kevin has 15 phones that need to be repaired. By the afternoon, Kevin has successfully repaired 3 of the 15 phones and a client has dropped off 6 more phones that need fixing. If a coworker of Kevin's offers to help him and fix half of the damaged phones, how many phones will each person need to repair?

### Response:
 Kevin anaanza siku na simu 15 na anarekebisha 3 kufikia mchana, hivyo Kevin bado anahitaji kurekebisha simu 15 - 3 = <<15-3=12>>12.
Mteja analeta simu 6 zaidi ambazo zinahitaji kurekebishwa, hivyo jumla ni 12 + 6 = 18 simu.
Ikiwa mfanyakazi mwenzake Kevin anamsaidia kurekebisha nusu ya simu, basi wote wawili watatakiwa kurekebisha 18 simu / 2 = <<18/2=9>>9 simu kila mmoja.
