Calculating the Number of Books Delivered to the Library

To calculate the number of books delivered to the library over 2 days, we can use the information provided.

1. Books Delivered on Day 1: 4/11 of all the books were delivered to the library. 2. Books Remaining on Day 2: 49 books were left after the first day.

To find out how many books were delivered in total, we can add the number of books delivered on the first day to the number of books remaining on the second day.

Calculation

- Books delivered on Day 1: 4/11 of all books - Books remaining on Day 2: 49 books

Solution

To find the total number of books delivered over 2 days, we can use the following steps: 1. Calculate the number of books delivered on the first day. 2. Add the number of books remaining on the second day to the number of books delivered on the first day.

Answer

The total number of books delivered to the library over 2 days is 73.

This calculation is based on the information provided and the formula: Books delivered on Day 1 + Books remaining on Day 2 = Total books delivered.
