How many walnut trees should be planted per acre to maximize the annual yield for the acre? What is the maximum number of pounds of walnuts per acre?
from what i assumed i set this up.
x= the number of trees per acre
f(x)= { 60x if x is less than or equal to 20}
{ 60x-2(x-20) if x is greater than 20}
i'm not sure if this is right or where to go from here.
