In the Greenwich Public Library, about one-tenth of the books are overdue when they are returned. An average of 580 books are returned to the library each day. About how many books could be expected to be returned on time each day?
1/10 * 580 = 58 late
so, the rest are on time
522
To find the number of books that could be expected to be returned on time each day, we need to subtract the number of overdue books from the total number of books returned.
Step 1: Find the number of overdue books.
Given that about one-tenth of the books are overdue, we can calculate this as:
Overdue books = (1/10) * Total books
Step 2: Calculate the number of books returned on time.
Books returned on time = Total books - Overdue books
Given that the average number of books returned to the library each day is 580, we can use this information to find the number of books returned on time.
Overdue books = (1/10) * 580
Overdue books = 58
Books returned on time = 580 - 58
Books returned on time = 522
Therefore, you could expect approximately 522 books to be returned on time each day at the Greenwich Public Library.
To find out how many books could be expected to be returned on time each day, we need to calculate 90% of the total number of books returned each day.
Here's how you can do it step-by-step:
Step 1: Calculate 90% of the total number of books returned each day
To find 90% of a value, you can multiply that value by 0.9.
In this case, we need to find 90% of 580 books, so we'll multiply 580 by 0.9:
90% of 580 = 580 * 0.9 = 522 books
Therefore, about 522 books could be expected to be returned on time each day in the Greenwich Public Library.
