What is the formula used to get the decreased amount?
the % change is found by dividing the amount changed by the original amount:
(19-20)/20 = -1/20 = -5%
Thank you so much for the help
To calculate the percentage decrease, you can use the following formula:
Percentage decrease = (Original amount - New amount) / Original amount * 100
In the given example:
Original amount = 20
New amount = 19
So, to calculate the percentage decrease:
Percentage decrease = (20 - 19) / 20 * 100
= 1 / 20 * 100
= 5%
Therefore, the decrease percentage is 5%.
