Thanks for posting your question! Let's solve your problem:

The answer to your question is: 280% increase!

When we do percent of change, we will set up this ratio.

 CHANGE IN QUANTITY (23 - 20)

------------------------------------------

  ORIGINAL QUANTITY (3)

The change in quantity is : 23 - 20

The original quantity would be 3, 23 - 20 = 3.

Now, we will convert that into a fraction.

20 / 2 = 10

23 - 20 = 3

Fraction - 3/10

Make the fraction into a decimal.

3/10 = 0.15

Make the decimal into the percent.

0.15 = 15% increase

Best of Luck!
