If the original quantity is 5 and the new quantity is 4, what is the percent decrease?

The answer is 20%

Step-by-step explanation:

5=100%

meaning if you decrease it by one each time it will look like this:

5=100%

4=80%

3=60%

2=40%

1=20%

so if it was decreased to four your answer is 20%

and you still have 80% remaining.
