Richard earns \( \$ 12.00 \) per hour at the coffee shop. After three months, his alary is increased to \( \$ 12.60 \) per hour. Express the change in Richard's salary as percent. Find the amount of the change in Richard's \( 12.60-12.00=0.60 \) salary. Evaluate the change relative to the original \( \frac{0.60}{12.00}=0.05=5 \% \) amount and express as a percent. Is this a percent increase or decrease? Richard's salary increased \( 5 \% \)

Step-by-step Solution

To find the change in Richard's salary as a percent, we can follow these steps: 1. **Calculate the change in salary**: \[ \text{Change in salary} = \text{New salary} - \text{Old salary} = 12.60 - 12.00 = 0.60 \] 2. **Evaluate the change relative to the original amount**: \[ \text{Percent change} = \frac{\text{Change in salary}}{\text{Old salary}} \times 100 = \frac{0.60}{12.00} \times 100 \] \[ \text{Percent change} = 0.05 \times 100 = 5\% \] 3. **Determine if this is a percent increase or decrease**: Since Richard's salary went from \( \$12.00 \) to \( \$12.60 \), this is an increase. Thus, Richard's salary increased by \( 5\% \).
