Let number of trees = t= 16 + x
Let apples = a = 300 - 10x, as there is 10 less apples, per extra tree.
yield = t x a
= (300 - 10x) x (16 + x)
= 4800 + 300 x - 160 x - 10 x^2
= -10x^2 + 140 x + 4800 QED
Probably the most helpful answer I've gotten. Many teachers and other students seemed adament that their idea was the best. But thanks, answers my question!
I've been hearing things of different people as to how many units to keep for year 12. I tend to drift towards 10 units, so I'd be able to concentrate on fewer subjects in more depth. Your thoughts?
