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

### Instruction:
John had $20. He spent 1/5 of his money on snacks and 3/4 of the remaining money on necessities. How much is left of John's money?

### Response:
 John alitumia $20 x 1/5 = $<<20*1/5=4>>4 kwa vitafunio.
Alibakiwa na $20 - $4 = $<<20-4=16>>16 pesa iliyobaki.
Alitumia $16 x 3/4 = $<<16*3/4=12>>12 kwa mahitaji muhimu.
Hivyo, John amebakiwa na $16 - $12 = $<<16-12=4>>4.
