find the producer's surplus at a price level of p=$150 for the price-supply equation p=S(x)=100-0.25x

is received p=200

the final answer is 5000 is this correct and can you do the steps so i can see if i did i correct

You have not defined x. Is S supposed to be Supply or Surplus? Why should it equal price (p)?

What is the mening of the partial statement <<is received p=200>>?

Is 5000 the book's answer or yours?
