Question

what is the percent of change from 20 to 32? 80% increase 60% increase 60% decrease 80% decrease

Explanation:

Step1: Recall percentage change formula

The formula for percentage change is $\frac{\text{New Value}-\text{Old Value}}{\text{Old Value}}\times100\%$.

Step2: Identify old and new values

Old value = 20, New value = 35.

Step3: Substitute into formula

Calculate numerator: $35 - 20 = 15$.
Then, $\frac{15}{20}\times100\% = 0.75\times100\% = 75\%$. Since new value > old value, it's an increase.

Answer:

75% increase
