Given:
Alan salary P (in dollars) when he works h hours is represented by the equation
![P=12.50h](https://tex.z-dn.net/?f=P%3D12.50h)
To find:
The earning per hour.
Solution:
We have,
![P=12.50h](https://tex.z-dn.net/?f=P%3D12.50h)
Here, P is total salary and h is number of hours he works.
![\text{Earning per hour}= \dfrac{\text{Total salary}}{\text{Number of hours}}](https://tex.z-dn.net/?f=%5Ctext%7BEarning%20per%20hour%7D%3D%20%5Cdfrac%7B%5Ctext%7BTotal%20salary%7D%7D%7B%5Ctext%7BNumber%20of%20hours%7D%7D)
![\text{Earning per hour}= \dfrac{12.50h}{h}](https://tex.z-dn.net/?f=%5Ctext%7BEarning%20per%20hour%7D%3D%20%5Cdfrac%7B12.50h%7D%7Bh%7D)
![\text{Earning per hour}=12.50](https://tex.z-dn.net/?f=%5Ctext%7BEarning%20per%20hour%7D%3D12.50)
Therefore, the earning per hour is $12.50.
