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

### Instruction:
Claire has 400 flowers in her garden. One hundred twenty are tulips, and the rest are roses. Eighty of the roses are white, while the rest are red. Each red rose is worth $0.75. How much will Claire earn if she can sell 1/2 of the total number of red roses?

### Response:
 Kwanza tafuta idadi ya waridi Claire anavyo: Maua 400 - tulips 120 = <<400-120=280>>280 waridi
Kisha tafuta idadi ya waridi nyekundu anavyo: Waridi 280 - waridi weupe 80 = <<280-80=200>>200 waridi nyekundu
Kisha gawanya idadi ya waridi nyekundu kwa 2: Waridi 200 nyekundu / 2 = <<200/2=100>>100 waridi nyekundu
Kisha multiply idadi ya waridi nyekundu na bei ya kila waridi: Waridi 100 nyekundu * $0.75 = $<<100*0.75=75>>75
