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

### Instruction:
George is about to celebrate his 25th birthday. Since his 15th birthday, he's been given a special $1 bill from his parents. They told him that on his 25th birthday, for every bill he still has, they will give him $1.5 in exchange. He spent 20% of his special bills. How much will he receive from his parents when he exchanges them?

### Response:
 Alipokea noti maalum 2 kwa sababu 25 - 15 = <<25-15=10>>10.
Alichagua noti 2 kwa sababu 10 x .2 = <<10*.2=2>>2.
Ana noti 8 zilizobaki kwa sababu 10 - 2 = <<10-2=8>>8.
Wazazi wake watampa $12 kwa noti hizo kwa sababu 8 x 1.5 = <<8*1.5=12>>12.
