Answer 2

To find the percentage decrease, you need to first find the decrease, and then find how much that is in relationship to the original value. It dropped from $2.86 to $2.81, so the decrease is $0.05. You divide the decrease, $0.05, with the original price, $2.86, to find the percentage decrease. Multiply that value by 100 to get the value in percent.
