Calculation of the Total Number of Books Borrowed

To calculate the total number of books borrowed by the students in the school library over three days, we need to add up the number of books borrowed on each day.

1. Thursday: 17 books were borrowed. 2. Friday: 15 more books were borrowed than on Thursday. Therefore, the number of books borrowed on Friday is 17 + 15 = 32. 3. Saturday: The number of books borrowed on Saturday is twice the combined total of books borrowed on Thursday and Friday. Therefore, the number of books borrowed on Saturday is (17 + 32) * 2 = 98.

To find the total number of books borrowed over the three days, we add up the number of books borrowed on each day: 17 + 32 + 98 = 147.

Therefore, the students borrowed a total of 147 books in the library over the three days.
