The monthly demand model for a refrigerator is given by N = -8p + 20000. The monthly supply model for the same refrigerator is N = 10p + 4250. For these models, p is the price of the refrigerator and N is the number of refrigerators sold or supplied each month by the store. Find the price at which supply and demand are equal (break-even point). At this price, how many refrigerators can be supplied and sold each month?
