First, solve for the difference between the two prices. That is, $2.79 - $2.86 which is equal to -$0.07. Divide this value by the original price and multiply by 100%. This is shown below,                          (-$0.07 / $2.86) x100% = -2.448% Thus, the percentage decrease is approximately equal to 2.4%.
