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

### Instruction:
Rohan owns a 20-square meter coconut farm. Each square meter has 2 coconut trees and each tree has 6 coconuts. If the coconuts can be harvested every 3 months and each coconut costs $0.50, how much will he earn after 6 months?

### Response:
 Rohan ana jumla ya miti ya nazi 20 x 2 = <<20*2=40>>40.
Na ana jumla ya nazi 40 x 6 = <<40*6=240>>240.
Hivyo, jumla ya nazi atakayokuwa nayo baada ya miezi 6 ni 240 x 2 = <<240*2=480>>480.
Hivyo, jumla ya kiasi atakachopata ni 480 x $0.50 = $<<480*0.5=240>>240.
