C. finding the number of books remaining after a sale on books
The scenario that represents finding the difference is C. finding the number of books remaining after a sale on books.
To understand why this represents finding the difference, let's break it down. "Finding the difference" typically involves comparing two quantities and determining the numerical gap or discrepancy between them. In this case, we are comparing the number of books before and after a sale.
To find the difference, you would need to:
1. Determine the initial number of books in the store before the sale.
2. Determine the number of books sold during the sale.
3. Subtract the number of books sold from the initial number of books to find the remaining quantity.
By performing this subtraction, you are essentially finding the difference between the initial quantity (before the sale) and the final quantity (after the sale). So, scenario C. finding the number of books remaining after a sale on books is an example of finding the difference.
