Chapter 0, Problem 68PO

To determine

To find the number of comic books Drew need to have to have a larger collection than Connar.

Answer to Problem 68PO

Therefore Drew must have at least 28 books to have a larger collection than Connar & option C is correct.

Explanation of Solution

Given:

Drew currently has 31 comic books in his collection & Connar has 58 comic books.

Calculation:

Let the required number of books that Drew have be x.

Then,

  $31+x>58$

Subtracting 31 on both sides, we get

  $\begin{array}{l}31+x-31>58-31\\ \Rightarrow x>27\end{array}$

Therefore Drew must have at least 28 books to have a larger collection than Connar.

Hence option C is correct.
