The price of an item yesterday was 180. Today, the price rose to 207 . Find the percentage increase.

Answer 1

To determine the percentage increase, you need to subtract the two prices, divide the difference by the original price, then multiply by 100.

For this problem: (207 - 180) * 100 = 27 * 100 = 15 % increase

180 180

To check, 15% of $180 is $27 and this is indeed the amount the price went up.
