B) Suppose v = $200 (implicit daily rental price of an (armored) vehicle) and w (per day) = $300. What is the minimum cost associated with producing 60 deliveries (q = 60)? Draw the "equal-cost line" associated with these input prices this cost (label it "CB"). Below write the optimal amounts of k and l (you should see this clearly in your graph), and the total cost of 60 deliveries
