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

### Instruction:
Sasha heard that planting trees helps to reduce the local temperature. For each tree planted, the temperature drops .1 degree. A tree costs $6 to plant. If she got the local temperature to drop from 80 to 78.2, how much did it cost to plant the trees?

### Response:
 Joto lilishuka kwa digrii 1.8 kwa sababu 80 - 78.2 = <<80-78.2=1.8>>1.8
Alipanda miti 18 kwa sababu 1.8 / .1 = <<1.8/.1=18>>18
Iligharimu $108 kupanda miti kwa sababu 18 x 6 = <<18*6=108>>108
