The price of a cup of coffee has dropped to $2.20 today. yesterday's price was $2.55. find the percentage decrease. round your answer to the nearest tenth of a percent.

Percentage decrease = (original number - new number) / original number...* 100

percentage decrease = (2.55 -2.20) / 2.55* 100
                                      0.35 / 2.55* 100
                                      0.137 * 100
                                      13.7% decrease <===
