After one year on the job, Grady got a raise from \( \$ 15.50 \) to \( \$ 16.12 \) per hour. What was the percent increase in his hourly wage? The percent of increase was \( \square \% \).

To find the percent increase in Grady's hourly wage, we can use the formula: \[ \text{Percent Increase} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100\% \] Given: - Old Value (hourly wage before the raise) = $15.50 - New Value (hourly wage after the raise) = $16.12 Substitute the values into the formula: \[ \text{Percent Increase} = \left( \frac{16.12 - 15.50}{15.50} \right) \times 100\% \] Now, we can calculate the percent increase in Grady's hourly wage. Calculate the value by following steps: - step0: Calculate: \(\frac{\left(16.12-15.5\right)}{15.5}\times 100\) - step1: Remove the parentheses: \(\frac{16.12-15.5}{15.5}\times 100\) - step2: Subtract the numbers: \(\frac{0.62}{15.5}\times 100\) - step3: Divide the terms: \(\frac{1}{25}\times 100\) - step4: Reduce the numbers: \(1\times 4\) - step5: Simplify: \(4\)
