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

### Instruction:
 Linda alinunua vitabu viwili vya rangi kwa $4 kila kimoja, pakiti 4 za karanga kwa $1.50 kila pakiti, na kiumbe kizima. Alimpa muuzaji $25 na hakupata mabadiliko. Kiumbe kizima kina gharama kiasi gani?


### Response:
 Vitabu viwili vya rangi vina gharama ya 2 x $4 = $<<2*4=8>>8.
Pakiti 4 za karanga zina gharama ya 4 x $1.50 = $<<4*1.5=6>>6.
Jumla ya gharama ya vitabu vya rangi na karanga ni $8 + $6 = $<<8+6=14>>14.
Hivyo, kiumbe kizima kina gharama ya $25 - $14 = $<<25-14=11>>11.
