A company produces a walkie-talkie communications device for use in industrial settings.  The fixed cost (C_F) is $60,000 per month, and the variable cost (C_V) is 85 per unit.  The selling price per unit is  P = $165 – 0.016(D), in which D is the demand or number of units sold.  Determine the optimal volume for this product; that is, the value of demand D at which profit is maximized.
