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

### Instruction:
When the strawberries at Fruity Farm are ready for harvest, Miguel charges each interested picker $4 to access the strawberry fields. Once there, people pick as many strawberries as they wish, and then take them to Miguel for weighing and pricing. This year, the standard price of a pound of strawberries is $20. Miguel is a very generous man. He deducts the entrance charge from the cost of the harvest. Sally, Jenny and Moses have just finished their strawberry picking and are headed home. They paid $128 for their harvest. How many pounds of strawberry did they pick?

### Response:
 Ili kupata ufikiaji wa mashamba ya stoberi, Sally, Jenny na Moses walilipa jumla ya $4 * 3 = <<4*3=12>>12 dola.
Kwa hivyo gharama kabla Miguel hajapunguza $12 ilikuwa $128 + $12 = <<128+12=140>>140 dola.
Walichuma pauni 140/20 = <<140/20=7>>7 za stoberi
