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

### Instruction:
 Dada wa Natalie alikuwa na vitabu vidogo 8 katika kabati yake. Msimu uliopita alinunua mara mbili idadi ya vitabu alivyokuwa navyo na kisha akapoteza 1/4 ya alivyokuwa navyo. Dada wa Natalie ana vitabu vingapi sasa?


### Response:
 Dada wa Natalie alinunua 2 * 8 vitabu = <<2*8=16>>16 vitabu.
Hivyo, alikuwa na vitabu 16 + 8 vitabu = <<16+8=24>>24 vitabu.
Baadaye, alipoteza 1/4 * 24 vitabu = <<1/4*24=6>>6 vitabu.
Hivyo, sasa ana vitabu 24 vitabu - 6 vitabu = <<24-6=18>>18 vitabu.
