Hill crest public elementary school was recycling their copier paper after the students had completed the worksheets.They found that when they filled a barrel with paper,it weighed an average of 225 kilograms if they collected 16 barrels of paper during the year.What was the approximate weight of the paper?if they receive $25 for every 400 kilograms, how much money would they receive?

225 x 16= 3600

3600/400=9
9 x $25 = $225

To determine the approximate weight of the paper, we need to find the total weight of the 16 barrels. Since each barrel weighs an average of 225 kilograms, we can multiply this weight by the number of barrels:

Total weight of the paper = 16 barrels × 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 ÷ 400 kilograms
Number of 400-kilogram chunks = 3600 kilograms ÷ 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 × Amount per chunk
Total money received = 9 chunks × $25
Total money received = $225

Therefore, they would receive approximately $225 for recycling the paper.
