Question 20
The price of a cup of coffee was $2.65 yesterday. Today, the price fell to
$2.50. Find the percentage decrease. Round your answer to the nearest tenth of a percent.
We must find the difference between prices. $2.65 - $2.50 = $0.15. Now we need to calculate what percent $0.15 is of $2.65. It is 5.7%! The price decreased, so it is a 5.7% decrease!
