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

### Instruction:
Jeff wanted to rent an apartment to live in for the next 5 years until he finishes his studies. He found a nice apartment next to his school, the owner asks Jeff to pay $300 each month, Jeff agreed, and for the first 3 years everything went fine, but then the owner wanted to raise the price for each month to $350. Jeff agreed again and continued paying until he graduated. How much did Jeff end up paying for the apartment throughout the 5 years?

### Response:
 Kwanza Jeff alilipa, $300/mwezi x 12 miezi = $<<300*12=3600>>3,600/mwaka.
Kwa miaka 3 ya kwanza, alilipa $3,600/mwaka x 3 miaka = $10,800.
Miaka 2 ya mwisho, Jeff alilipa $350/mwezi x 12 miezi = $<<350*12=4200>>4,200/mwaka.
Kwa miaka 2 ya mwisho, alilipa $4,200/mwaka x 2 miaka = $8,400.
Alimaliza kulipa $10,800 + $8,400 = $<<10800+8400=19200>>19,200.
