Since we are looking for the smallest possible value of d, we can let v = 2 and b = 3. That is, a pound of lobster can make 2 vats of lobster bisque and each vat makes 3 bowls of lobster bisque. Therefore, a pound of lobster can make 6 bowls of lobster bisque. We can assume that the cost of each bowl of lobster bisque is $1. So 6 bowls = $6. In other words, a pound of lobster makes $6, so 6 pounds of lobster is (at least) $36.
