Answer

So, the demand $x$ as a function of the price $p$ is $x= \boxed{25000 - 500p}$.

Steps

Step 1 ：The given price-demand equation is $p+0.002x=50$.

Step 2 ：We need to express the demand $x$ as a function of the price $p$.

Step 3 ：To do this, we subtract $p$ from both sides of the equation to get $0.002x = 50 - p$.

Step 4 ：Then, we divide both sides of the equation by $0.002$ to isolate $x$.

Step 5 ：This gives us the function $x = 25000 - 500p$.

Step 6 ：So, the demand $x$ as a function of the price $p$ is $x= \boxed{25000 - 500p}$.
