Answer:

31% decrease

Step-by-step explanation:

To find the rate of increase or decrease, you need to plug this equation in.

(Greater Value - Lesser Value)/Old Value

In this situation, the greater value is 72, the lesser value is 50, and the old value is 72.

(72 - 50)/72 = 22/72

                    = 11/36

                    = 0.31 or 31% of a decrease.
