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

### Instruction:
Bugs are thriving in a garden of 30 plants. The bugs are very hungry today and completely ate 20 plants. The next day, they were still full and only ate half of the remaining plants. After that, they ate only 1 of the plants that were left. How many plants remain?

### Response:
 Kulikuwa na mimea 30 kabla wadudu hawajala yoyote.
Wadudu walila mimea 20 siku ya kwanza.
Hivyo kuna mimea 30-20=<<30-20=10>>10 iliyosalia.
Siku inayofuata, waliila nusu ya mimea iliyosalia.
Hiyo ni 10/2=<<10/2=5>>5 mimea.
Hivyo kuna 10-5=<<10-5=5>>5 mimea iliyosalia.
Walila mimea 1 iliyosalia.
Hivyo kuna 5-1=<<5-1=4>>4 mimea iliyosalia.
