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

### Instruction:
Adam's father deposited $2000 in the bank. It receives 8% interest paid throughout the year, and he withdraws the interest as soon as it is deposited.  How much will Adam’s father have, including his deposit and the interest received after 2 and a half years?

### Response:
 Riba ya kila mwaka ni 2000/100= <<2000/100=20>>20 %.
Riba kwa miaka miwili na nusu ni 20/100 * 2000 = $400.
Hivyo, Baba ya Adam atakuwa na $2000 + $400 = $<<2000+400=2400>>2400 baada ya miaka 2 na nusu.
