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

### Instruction:
A pack of pretzels costs $4, while a pack of chips is 75% more expensive. Maciek went and bought two packets of chips and two packets of pretzels. How much did he pay for his purchases?

### Response:
 Pakiti moja ya chips inagharimu 75/100 * 4 = $<<75/100*4=3>>3 zaidi ya pakiti moja ya pretzels.
Hii inamaanisha pakiti moja ya chips inagharimu 4 + 3 = $<<4+3=7>>7
Hivyo Maciek alilipa 4 + 7 + 4 + 7 = $<<4+7+4+7=22>>22 kwa manunuzi yake.
