Sagot :
First we subtract it:
18 - 15 = 3
Now we divide it to the original:
3 / 15 = 0.2
Multiply by 100:
0.2 * 100 = 20%
18 - 15 = 3
Now we divide it to the original:
3 / 15 = 0.2
Multiply by 100:
0.2 * 100 = 20%
Answer:
20%
Step-by-step explanation:
percent of change = amount of change/original amount
First, subtract (to get the amount of change) 18 - 15 = 3
Plug numbers in according to the formula above 3/15
Simplify 1/5
1/5 x 100 = 100/5
Divide: 20
The answer is 20%
