Problem Analysis

We are given that a printing press prints the same number of books daily and that it printed 940 books in 4 days. We need to determine the total number of books that need to be printed if there are 9 days left to complete the task.

Solution

To find the total number of books that need to be printed, we can use the following equation:

Total number of books = (Number of books printed per day) × (Number of days)

Given that the printing press prints the same number of books daily, we can calculate the number of books printed per day by dividing the total number of books printed in 4 days by 4:

Number of books printed per day = (Number of books printed in 4 days) / 4

Substituting the given values, we have:

Number of books printed per day = 940 / 4

Now, we can calculate the total number of books by multiplying the number of books printed per day by the number of remaining days:

Total number of books = (Number of books printed per day) × (Number of remaining days)

Substituting the given values, we have:

Total number of books = (940 / 4) × 9

Let's calculate the total number of books:

Total number of books = (940 / 4) × 9

Using a calculator, we find that the total number of books that need to be printed is 2,115.

Therefore, if there are 9 days left to complete the task, the printing press needs to print a total of 2,115 books.

Answer

If there are 9 days left to complete the task, the printing press needs to print a total of 2,115 books.
