To formulate the inequality regarding the number of books Jerrica can put in the box, we start with the information provided:
- The maximum weight the box can hold is 65 pounds.
- The weight of the container already in the box is 26 pounds.
- Each book weighs 1.3 pounds.
Let \( x \) represent the number of books Jerrica can add to the box. The total weight of the container and the books can be expressed as:
\[ 26 + 1.3x \]
Since this total weight cannot exceed 65 pounds, we write the inequality:
\[ 26 + 1.3x \leq 65 \]
To solve for \( x \), we first subtract 26 from both sides:
\[ 1.3x \leq 39 \]
Next, we divide both sides by 1.3:
\[ x \leq \frac{39}{1.3} \]
Calculating \( \frac{39}{1.3} \):
\[ \frac{39}{1.3} = 30 \]
Thus, we have the inequality:
\[ x \leq 30 \]
Summary of the Solution:
Jerrica can put at most 30 books in the box. The solutions to the inequality represent all the possible whole numbers of books \( x \) that Jerrica can place in the box, which are \( 0, 1, 2, \ldots, 30 \).
