100*12/15 = 80 percent
The class enrollment increased by 3 students. This is the equivalent of 20%.
A 25% increase
25% increase from 12 to 15. 20% decrease from 15 to 12.
15% of 80 = 80*15/100 = 12 So, an increase of 15% is 80+12 = 92
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
A 15 percent increase of 11.50 gives a new value of 13.23
80 percent of 12 percent = 0.8 x 12 percent = 9.6 percent
To increase a number by a certain percent, multiply it by (1 + n/100). For example, to increase a number by 15 percent, multiply it by (1 + 15/100), or 1.15. To decrease a number by 15 percent, multiply it by (1 - 15/100), or 0.85.
