X + 20 <= √x + 9
x <= √x - 11
This can't be true without using imaginary numbers...
Any number of x greater than 0 will result in a false statement
Any number of x less than 0 will result in an imaginary number because of √x
Divide total price by gallons:
82.15 / 31 = 2.65 for 1 gallon

Answer: 17%</h3>
====================================================
Explanation:
The change in value is 30-25 = 5, so the amount has dropped by 5
Divide this change over the original amount to get 5/30 = 0.1667 approximately. This converts to 16.67% roughly, and that rounds to 17%
----------------
Here's a way to do it using a formula
A = old value = 30
B = new value = 25
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (25-30)/30 ] * 100%
C = -0.1667 * 100%
C = -16.67%
C = -17%
The negative percent change means we have a percent decrease. The class size went down by about 17%.
