A Better Whale Mold? Suppose a new mold is developed for producing fake killer whales. The new mold has twice the cost of the original mold, but cuts the marginal cost of whales to $1,000. (Related to Application 3 on page 531.)

a. How does the cost of the first whale produced with the new mold compare to the cost with the original mold?

b. At what quantity of whales will production with the new mold be less costly than production with the original mold?
