In a certain region, the number of bushels of corn per acre, B, is given by the function B(n)=-0.1n^2 + 10n, where n represents the number of seeds, in thousands, planted per acre.
If corn sells for $3/bushel and cost $2 for 1000 seeds, find the optimal number of seeds to be planted per acre.
I need help please!!!
