Sylvia has an apple orchard. One season, her 100 trees yielded 140 apples per tree. She wants to increase her production by adding more trees to the orchard. However, she knows that for every 10 additional trees she plants, she will lose 2 apples per tree (i.e., the yield per tree will decrease by 2 apples). How many trees should she have in the orchard to maximize her production of apples?
