This store gets its ground beef from local ranchers. If the store is willing to pay the ranchers $2.00 per pound for their ground beef, the ranchers are only willing to sell 100 pounds of ground beef each day. (Some ranchers won’t sell them any, and those who will have a limited amount available.) If they raise the price to $4.00 per pound, the ranchers will sell the store 500 pounds of ground beef each day. Assuming a linear relationship between the price per pound of ground beef and the supply (in pounds), find a model for the s, the daily supply of ground beef as a function of p, the price in dollars for one pound.
