Answer to Problem 27STP

Number of months will Paul have a total $44$ books in his collection is $8$ months.

Explanation of Solution

Given information:

 A. $5$

 B. $6$

 C. $8$

 D. $15$

Let the number of months in which a person increases their book collection by $3$ books he represented by $X$ .

If the person starts with $20$ books and wants to have a total of $44$ books the situation can be represented by the equation $44=20+3X$ .

For finding number of months that the person requires to have a total of $44$ books,

  $44=20+3X$ for $X$

  $\begin{array}{l}3X=44-20\\ X=\frac{24}{3}\\ X=8months\end{array}$

Therefore, correct answer is $8$ months that is option (H).
