To calculate the percentage increase in a worker's salary, you can use the following formula:
\[ \text{Percentage Increase} = \left( \frac{\text{New Salary} - \text{Old Salary}}{\text{Old Salary}} \right) \times 100 \]
In this case, the old salary is #5000, and the new salary is #8000.
-
Calculate the increase in salary: \[ \text{Increase} = \text{New Salary} - \text{Old Salary} = 8000 - 5000 = 3000 \]
-
Now, apply the values to the formula: \[ \text{Percentage Increase} = \left( \frac{3000}{5000} \right) \times 100 \]
-
Simplify the fraction: \[ \frac{3000}{5000} = 0.6 \]
-
Now, multiply by 100 to get the percentage: \[ 0.6 \times 100 = 60% \]
The percentage increase in the worker's salary is 60%.
