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?
To gain entry into the strawberry fields, Sally, Jenny and Moses paid a total of 4 * 3 = <<4*3=12>>12 dollars
This means that before Miguel applied the $12 discount, the cost was 128 + 12 = <<128+12=140>>140 dollars
We get the weight by dividing the cost by the price of strawberries per pound, 140/20 = <<140/20=7>>7 pounds
