there were 12 stray cats in a town. one year later, there were 21 stray cats in the town. what was the percent change? ?%

Answer

Explanation:

Step1: Find the amount of change

$21 - 12=9$

Step2: Use the percent - change formula

Percent change=$\frac{\text{amount of change}}{\text{original amount}}\times100%$. The original amount is 12 and the amount of change is 9. So, $\frac{9}{12}\times100%$.

Step3: Simplify the fraction and calculate the percentage

$\frac{9}{12}=\frac{3}{4}=0.75$, and $0.75\times100% = 75%$

Answer:

75%
