A school library had 1050 books last year. There are only 950 books in the library this year. What is the percentage decrease in the number of books? Round your answer to 2 decimal places.
1050-950=100
100/1050*100 = 0.95%
That should be 9.5%
To find the percentage decrease in the number of books, we can use the following formula:
Percentage decrease = (Change in value / Initial value) * 100
First, we need to calculate the change in value. In this case, the change is the difference between the initial value and the final value.
Change in value = 1050 - 950 = 100
Now, we can substitute the values into the formula:
Percentage decrease = (100 / 1050) * 100 ≈ 9.52
Therefore, the percentage decrease in the number of books is approximately 9.52%.
