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

### Instruction:
Ahmed has 8 orange trees and four times as many apple trees in his orchard as Hassan. If Hassan has one apple tree and two orange trees, and they both have only apple and orange trees in their orchards, how many more trees are in Ahmed's orchard than in Hassan's?

### Response:
 Hassan ana mti mmoja wa tofaa na miti miwili ya machungwa, hivyo ana jumla ya miti 1 + 2 = <<1+2=3>>3.
Ahmed ana miti mara nne ya tofaa kama Hassan, hivyo ana miti 4*1 = 4 ya tofaa.
Ahmed ana miti mara nne ya machungwa kama miti ya tofaa, hivyo ana miti 4*4 = 16 ya tofaa.
Ahmed ana jumla ya miti 4 + 16 = <<4+16=20>>20.
Hassan ana miti 3, hivyo Ahmed ana miti 20 - 3 = <<20-3=17>>17 zaidi ya miti ya Hassan.
