A company has two factories that produce lawnmowers, which sell for $600 apiece. The cost of the first factory producing 1 lawnmowers is 1000 + 300x + 3zº. The cost of the second factory producing y lawnmowers is 3000 + 200y + 2y? Therefore, if the first factory produces a lawnmowers and the second factory produces y lawnmowers, the revenue is R(x, y) = 6002 + 600y, and the cost is C(x, y) = 1000 + 300x + 3x + 3000 + 200y + 2y? Find the values of u and y that maximize the profit. (Give your answer as an ordered pair (x,y).)
