Question:

The corn yield on a certain farm is Y = −0.118x+ 8.5x + 12.9 (bushels per acre) where x is the number of corn plants per acre (in thousands). Assume that corn seed costs $1.25 (per thousand seeds) and that corn can be sold for $1.50/bushel. Let P(x) be the profit (revenue minus the cost of seeds) at planting level x.
(a) Compute P(x0) for the value x0 that maximizes yield Y.
(b) Find the maximum value of P(x). Does maximum yield lead to maximum profit?
