Answer:
Step-by-step explanation:
Let's solve this problem step-by-step. The library had 1,500 books in 2011. The ratio of books in 2011 and in 2012 is 1:2. Therefore, let the number of books in 2012 be .
We have the following proportion:
Therefore, there were 3,000 books in 2012. The ratio of books in 2012 and in 2013 is 2:5. Let the number of books in 2013 be .
We have:
Therefore, there were 7,500 books in 2013.
You can use the associative property with addition and multiplication operations, but not subtraction of division, only some times.
The third choice:
f(0) = g(-2)
