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

### Instruction:
 Kuna taa nne katika chumba cha Valerie. Zote zimezimika, hivyo anahitaji kununua balbu mpya. Anahitaji balbu tatu ndogo na balbu moja kubwa. Ana $60 za kutumia. Ikiwa balbu ndogo zina gharama ya $8 na balbu kubwa inagharimu $12, Valerie atabakiwa na pesa ngapi?


### Response:
 Balbu ndogo zitamgharimu Valerie jumla ya 3 * $8 = $<<3*8=24>>24.
Jumla ya balbu nne itagharimu $24 + $12 = $<<24+12=36>>36.
Jumla ya pesa ambazo Valerie atabakiwa nazo ni $60 - $36 = $<<60-36=24>>24.
