A shipping company uses the weight of packages to determine shipping prices. For any item 5 pounds or greater, the following equation gives the price, p(w), of shipping the item between two locations as a function of the item's weight, w, in pounds. The company does not use the following equation to determine shipping prices for items which are greater than 80 pounds. Determine the domain of p(w). A. 5 ≤ w ≤ 80 B. 5 ≤ w ≤ 100 C. 0 ≤ w ≤ 100 D. 5 ≤ w ≤ 70
