I need help with solving the answer to the problem below.


What is the percent decrease, to the nearest percent, of the number of books checked out from June to July? June - 623(# of books checked out)
July - 715(# of books checked out)

Since more books were checked out in July, there was an increase.

How do I solve this problem? The answer I have is 715-623 = 92 or 92%. Is this the correct answer?

There is no correct answer as you posted the problem. There's an increase from June to July, not a decrease.

Ms. Sue,

Thank you so much for explaining.

You're welcome, Tina.

To calculate the percent decrease between June and July, you need to find the difference in the number of books checked out and express it as a percentage of the original quantity.

First, determine the decrease in the number of books checked out:

Decrease = June - July
= 623 - 715
= -92

Since the decrease is negative, it means there was a decrease in the number of books checked out.

Next, you need to find the percent decrease. To do this, you'll divide the decrease by the original quantity and multiply by 100:

Percent Decrease = (Decrease / June) * 100

Plug in the values:

Percent Decrease = (-92 / 623) * 100

Calculating this expression, you can find:

Percent Decrease ≈ -14.8

To the nearest percent, the percent decrease is -15%.

Therefore, the answer to the problem is that the percent decrease, to the nearest percent, of the number of books checked out from June to July is approximately 15%.
