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

### Instruction:
Ivan had $10 and spent 1/5 of it on cupcakes. He then spent some money on a milkshake and had only $3 left. How much is the milkshake?

### Response:
 Ivan alitumia 1/5 x $10 = $<<1/5*10=2>>2 kwa kununua keki.
Kwa kuwa alikuwa na $3 zilizobaki, basi jumla ya pesa alizotumia kwa keki na maziwa ya kuchanganya ni $10 - $3 = $<<10-3=7>>7.
Hivyo, $7 - $2 = $<<7-2=5>>5 zilitumika kununua maziwa ya kuchanganya.
