Question: Carlos knows from experience that by planting 36 mandarin orange trees on the one-acre grove that he owns, he can expect each tree to produce 200 oranges during the annual growing season. He also knows that each extra tree he squeezes into the grove would reduce the yield by four oranges per tree annually. If he would like to optimize his yield from these trees, how many trees should he plant to achieve a maximum crop, and what is that yield per tree?
