Calculate percent change of the temperature drops from 85 degrees to 65 degrees

23.5

Step-by-step explanation:

Percent change basically means what percent of the first number is the difference between the two numbers.

So the difference is 85-65 = 20.  20 is what percent of 85?  TO find this let's make it an algebra problem with x being multiplies by 85 to get 20

85x = 20

85 = .235

As a percent this is 23.5

So if we take 23.5% of 85 away from 85 we get 65.
