Answer:
![P(x)=8x-150](https://tex.z-dn.net/?f=P%28x%29%3D8x-150)
Step-by-step explanation:
Let
x-----> the number of shirts
we know that
The equation of the cost is equal to
![C(x)=2x+150](https://tex.z-dn.net/?f=C%28x%29%3D2x%2B150)
The equation of the sell is equal to
![S(x)=10x](https://tex.z-dn.net/?f=S%28x%29%3D10x)
The equation of the profit is equal to
![P(x)=S(x)-C(x)](https://tex.z-dn.net/?f=P%28x%29%3DS%28x%29-C%28x%29)
substitute the values
![P(x)=10x-(2x+150)=8x-150](https://tex.z-dn.net/?f=P%28x%29%3D10x-%282x%2B150%29%3D8x-150)
