Answer:
the number of trees planted is 37
Explanation:
The computation of the number of trees planted is shown below:
Let us assume the number of tree planted be x
Now the extra trees would be
= x - 24
And, the tree yield is 600 apples also the tree decrease by 12 per year
Now the equation is
y = x(600 - 12(x - 24))
y = -12x^2 + 888x
y = -24 + 888x
x = 37
Hence, the number of trees planted is 37
