Answer

Explanation:

Step1: Set up an equation

Let $h$ be the number of hours. The total earnings equation is $40 + 25h=127.50$.

Step2: Isolate the term with $h$

Subtract 40 from both sides: $25h=127.50 - 40$. So, $25h = 87.50$.

Step3: Solve for $h$

Divide both sides by 25: $h=\frac{87.50}{25}=3.5$.

Answer:

3.5
