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

### Instruction:
 Harry ameamua kununua baadhi ya mabaluni kwa ajili ya sherehe ya kuzaliwa ya rafiki yake. Baluni moja inagharimu $0.5, na pakiti ya maballuni 10 ni nafuu na inagharimu $3 tu. Hatimaye, Harry anataka kuleta sherehe maballuni 14 tu. Alilazimika kulipa kiasi gani kwa ajili yao?


### Response:
 Kununua maballuni 14, Harry anapaswa kununua pakiti moja ya 10, na maballuni 14 - 10 = <<14-10=4>>4 tofauti.
Bei ya maballuni 4 ni 4 * 0.5 = $<<4*0.5=2>>2.
Jumla ya gharama ya pakiti na maballuni tofauti itakuwa $3 + $2 = $<<3+2=5>>5.
