225 x 16= 3600
3600/400=9
9 x $25 = $225
3600/400=9
9 x $25 = $225
Total weight of the paper = 16 barrels ร 225 kilograms/barrel
Total weight of the paper = 3600 kilograms
Therefore, the approximate weight of the paper is 3600 kilograms.
Now, let's calculate the amount of money they would receive. Given that they receive $25 for every 400 kilograms of paper, we can determine the number of 400-kilogram "chunks" in 3600 kilograms:
Number of 400-kilogram chunks = Total weight of the paper รท 400 kilograms
Number of 400-kilogram chunks = 3600 kilograms รท 400 kilograms
Number of 400-kilogram chunks = 9
So they have a total of 9 "chunks" of 400 kilograms each. Now we can calculate the total amount of money:
Total money received = Number of chunks ร Amount per chunk
Total money received = 9 chunks ร $25
Total money received = $225
Therefore, they would receive approximately $225 for recycling the paper.
