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

### Instruction:
The county fair was hosting a pumpkin contest to see who could grow the biggest pumpkin in pounds.  Brad entered his pumpkin with a weight of 54 pounds.  Jessica's was half the weight of Brad's.  Betty's pumpkin weight 4 times the amount of Jessica's pumpkin.  What is the difference between the heaviest and lightest pumpkin in  pounds?

### Response:
 Boga ya Brad ina uzito wa pauni 54.
Boga ya Jessica ina uzito wa pauni 54/2 = <<54/2=27>>27.
Boga ya Betty ina uzito wa pauni 27*4=<<27*4=108>>108.
Boga nzito zaidi ina uzito wa pauni 108 na boga nyepesi ina uzito wa pauni 27.
Tofauti ni 108-27=<<108-27=81>>81 pauni.
