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

### Instruction:
Harry decided to buy some balloons for his friend's birthday party. One balloon costs $0.5, and a pack of 10 balloons is cheaper and costs only $3. Finally, Harry wants to bring to the party exactly 14 balloons. How much did he need to pay for them?

### 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.
