Answer: There are 86 acres of old-growth trees.
Step-by-step explanation:
In order to answer the question, we need to calculate the 0.2% of 43,000.
We can calculate this stating that exists a linear relationship between the percentage and the amount of acres. We also need to state that 43,000 acres are the 100% of the acres.
Therefore, we can write the following equation to calculate the percentage :
If we solve the equation in terms of ''x'' :
We find that if 43,000 acres are the 100% of the acres ⇒ The 0.2% of the acres are 86 acres (in which there are old-growth trees).
