Question

ann works in a supermarket for 10.00 per hour. She received a raise to 12.00. What is the percent of change in her hourly pay?

Answer 1

To calculate the percent change in Ann's hourly pay, we can use the formula:

\[
\text{Percent Change} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100
\]

In this case:

- Old Value (initial pay) = $10.00
- New Value (new pay) = $12.00

Now plug in the values:

\[
\text{Percent Change} = \left( \frac{12.00 - 10.00}{10.00} \right) \times 100
\]

Calculating the difference:

\[
12.00 - 10.00 = 2.00
\]

Now plug that into the formula:

\[
\text{Percent Change} = \left( \frac{2.00}{10.00} \right) \times 100 = 0.20 \times 100 = 20\%
\]

So, the percent change in Ann's hourly pay is **20%**.
