a companys stock was selling at $30 a share. a month later, it is selling at $33 a share. what is the percent change?
Answer
Explanation:
Step1: Find the amount of change
$33 - 30=3$
Step2: Use the percent - change formula
Percent change=$\frac{\text{Amount of change}}{\text{Original amount}}\times100%$. The original amount is 30 and the amount of change is 3. So, $\frac{3}{30}\times100% = 0.1\times100%=10%$
Answer:
10%
