To determine

To find: the amount which is spent by N on books.

Answer to Problem 46SGR

N spent $24 on books.

Explanation of Solution

Given:

Spent books and pens =$36

$12 more on books

Calculation:

The objective of the problem is to find the amount which is spent by N on books.

Let n = the amount N spent on pens,

n + 12 = the amount N spent on books.

The required equation,

  $\begin{array}{l}n+n+12=36\\ 2n+12=36\\ 2n=36-12\\ 2n=24\\ n=\frac{24}{2}\\ n=12\end{array}$

The amount N spent on books $=12+12=24$

Hence,N spent $24 on books.

Conclusion:

Hence,N spent $24 on books.
