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

### Instruction:
Kathleen receives a weekly allowance for completing all of her chores. During middle school, her allowance was $2 more than $8 but during her senior year,  her allowance was $5 more than twice her middle school allowance. What is the percentage increase in Kathleen's weekly allowance?

### Response:
 Posho ya Kathleen katika shule ya upili ilikuwa $8 + $2 = $<<8+2=10>>10 kwa wiki.
Mara mbili ya posho yake katika shule ya upili ni $10 x 2 = $<<10*2=20>>20.
Hivyo, posho ya Kathleen wakati wa mwaka wake wa mwisho ni $20 + $5 = $<<20+5=25>>25.
Hivyo, ongezeko la asilimia katika posho yake ya kila wiki ni $25 - $10 / $10 x 100% = 150%.
