Question

what is the percent of change from 40 to 32? 20% increase 15% decrease 20% decrease 15% increase

Explanation:

Step1: Recall percent change formula

The formula for percent change is $\text{Percent Change} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100\%$. Here, the old value is 40 and the new value is 32.

Step2: Calculate the difference

First, find the difference: $32 - 40 = -8$. The negative sign indicates a decrease.

Step3: Apply the formula

Now, apply the percent change formula: $\frac{-8}{40} \times 100\% = -0.2 \times 100\% = -20\%$. The negative sign means a 20% decrease.

Answer:

20% decrease
