Final answer:
The question relates to calculating percentage change in salary, which is a Mathematics concept. An example is given where an hourly wage increase from $10 to $12 results in a 20% growth rate.
Step-by-step explanation:
The subject of this question appears to deal with salary growth and percentage change calculations, which falls under the umbrella of Mathematics, specifically applying to real-world financial situations. While the initial question seems to be incomplete, it implies that an employee's salary change or raise is to be calculated as a percentage.
As an example, let's consider a situation where an employee earns a $10 per hour wage and receives a $2 per hour raise. The percentage change or growth rate in their pay would be calculated as the raise divided by the original pay rate. This calculation can be represented by the formula:
Percentage Change = (Raise / Original Pay Rate) x 100
For the given example, the calculation becomes:
Percentage Change = ($2 / $10) x 100 = 0.20 x 100 = 20%
This method of calculating percentage change is important for understanding financial growth and managing personal finances.
