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

### Instruction:
 Tim ananunua kitabu cha maneno ya siri. Anajifunza maneno 10 kutoka kitabu hicho kila siku. Katika miaka 2, kitabu hicho kimeongeza idadi ya maneno anayoyajua kwa 50%. Anajua maneno mangapi awali?


### Response:
 Katika miaka 2 kuna siku 365*2=<<365*2=730>>730
Hivyo amejifunza maneno 730*10=<<730*10=7300>>7300
Alijua mara 2 ya idadi hiyo ya maneno awali
Hivyo alijua maneno 7300*2=<<7300*2=14600>>14600 awali
