Answer:
56 trees will make 10000 newspapers.
Step-by-step explanation:
Given:
One tree makes approximately 230 newspapers.
Now, for estimating how many newspapers will be made with 56 trees.
By multiplying 
trees with 
newspapers we get,
.
And, rounding 
to one significant number (1 S.F.) is 
.
Therefore, 56 trees will make 10000 newspapers.
Add 72, 75, and 83, which equal 230. Then, since there are three values, you divide the total (230) by 3, which would equal 76.6 (cont), therefore meaning they can only raise their average (using the three tests, from a base grade of 0) to a 76.6 percent (or 77 if teacher rounds grade)
