Answer:
108 books.
Step-by-step explanation:
Let the number of magazines = m
Let the number of books = b
<u>Given the following data;</u>
Total number of m & b = 162
<em>Translating the word problem into an algebraic equation, we have;</em>
......equation 1
......equation 2
<em>Substituting equation "1" into equation "2" we have;</em>
m = 54
Now to find the number of books;
![b = m + 54](https://tex.z-dn.net/?f=%20b%20%3D%20m%20%2B%2054)
Substituting the value of "m" into the equation, we have;
<em>b = 108</em>
<em>Therefore, the total number of books in the library is 108 books. </em>

Answer:
B.
Step-by-step explanation:
Given: expressions
To find: the expression whose value is closest to e
Solution:
Value of e is 2.718
![\left ( 1+\frac{1}{19} \right )^{19}=\left ( \frac{20}{19} \right )^{19}=2.65\\\left ( 1+\frac{1}{22} \right )^{22}=\left ( \frac{23}{22} \right )^{22}=2.659\\\left ( 1+\frac{1}{20} \right )^{20}=\left ( \frac{21}{20} \right )^{20}=2.653\\\left ( 1+\frac{1}{21} \right )^{21}=\left ( \frac{22}{21} \right )^{21}=2.656](https://tex.z-dn.net/?f=%5Cleft%20%28%201%2B%5Cfrac%7B1%7D%7B19%7D%20%5Cright%20%29%5E%7B19%7D%3D%5Cleft%20%28%20%5Cfrac%7B20%7D%7B19%7D%20%5Cright%20%29%5E%7B19%7D%3D2.65%5C%5C%5Cleft%20%28%201%2B%5Cfrac%7B1%7D%7B22%7D%20%5Cright%20%29%5E%7B22%7D%3D%5Cleft%20%28%20%5Cfrac%7B23%7D%7B22%7D%20%5Cright%20%29%5E%7B22%7D%3D2.659%5C%5C%5Cleft%20%28%201%2B%5Cfrac%7B1%7D%7B20%7D%20%5Cright%20%29%5E%7B20%7D%3D%5Cleft%20%28%20%5Cfrac%7B21%7D%7B20%7D%20%5Cright%20%29%5E%7B20%7D%3D2.653%5C%5C%5Cleft%20%28%201%2B%5Cfrac%7B1%7D%7B21%7D%20%5Cright%20%29%5E%7B21%7D%3D%5Cleft%20%28%20%5Cfrac%7B22%7D%7B21%7D%20%5Cright%20%29%5E%7B21%7D%3D2.656)
Therefore, value 2.659 is closest to the value of e.
So, option B. is correct.
