Answer 1

Calculation of Books Bound by the Second Bookbinder

To determine the number of books bound by the second bookbinder, we need to use the information provided.

The first bookbinder bound 5 books per day and completed a total of 75 books.

Let's calculate the number of days it took for the first bookbinder to complete the task:

75 books / 5 books per day = 15 days

Since both bookbinders worked for the same number of days, we can conclude that the second bookbinder also worked for 15 days.

Now, let's calculate the number of books bound by the second bookbinder per day:

75 books / 15 days = 5 books per day

Therefore, the second bookbinder bound 5 books per day for a total of 75 books.
