Problem 2: Suppose a company's revenue function is given by R(q) = q3 + 230(12 and its cost function is given by C (q) = 220 + 18q where q is hundreds of blender's sold/produced, while R(q) and C(q) are in total dollars of revenue and cost, respectively. How many blenders need to be sold to maximize prots? What is the maximum prot? \"CHALLENGE\" Determine the price per blender when the profit is a maximum
