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

### Instruction:
Natalie bought some food for a party she is organizing. She bought two cheesecakes, an apple pie, and a six-pack of muffins. The six-pack of muffins was two times more expensive than the cheesecake, and one cheesecake was only 25% cheaper than the apple pie. If the apple pie cost $12, how much did Natalie pay for all her shopping?

### Response:
 Keki za jibini ziligharimu $12 * 75/100 = $<<12*75/100=9>>9 kila moja.
Pakiti sita za muffins ziligharimu $9 * 2 = $<<9*2=18>>18.
Jumla ya gharama ya ununuzi ni $9 + 9 + 18 + 12 = $<<9+9+18+12=48>>48.
