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

### Instruction:
It takes 320 rose petals to make an ounce of perfume. If each rose produces 8 petals, and there are 12 roses per bush, how many bushes will Fern have to harvest to make 20 12-ounce bottles of perfume?

### Response:
 Kwanza tafuta idadi ya waridi inayohitajika kwa unga wa manukato wa unga mmoja: pete 320 / pete 8/waridi = <<320/8=40>>40 waridi
Kisha unganisha idadi ya waridi inayohitajika kwa unga mmoja na idadi ya unga kwa kila chupa ili kupata idadi ya waridi kwa kila chupa: waridi 40/unga * unga 12/chupa = waridi 480/chupa
Kisha unganisha idadi hiyo na idadi ya chupa ili kupata idadi jumla ya waridi inayohitajika: waridi 480/chupa * chupa 20 = waridi 9600
Kisha gawanya idadi hiyo na idadi ya waridi kwa kichaka ili kupata idadi ya kichaka ambayo Fern anahitaji kuvuna: waridi 9600 / waridi 12/kichaka = <<9600/12=800>>800 kichaka
