A 25% increase
15% of 80 = 80*15/100 = 12
25% increase from 12 to 15. 20% decrease from 15 to 12.
The word increase means the problem is addition: 15 + x = 27. Reorder the problem so that it is subtraction: 27 - 15 = x and solve for x. X = 12.
Subtract the lower price from the higher one. Divide the difference by the original price. Multiply the answer by 100. Example: 15 dollars decreased to 12 dollars. 15 - 12 = 3 3/15 = 0.20 = 20 percent decrease Example: 12 dollars increased to 15 dollars. 15 - 12 = 3 3/12 = 0.25 = 25 percent increase
