37 Use LINDO to solve the Sailco problem of Section 3.10. Then use the output to answer the following questions:

a If month 1 demand decreased to 35 sailboats, what would be the total cost of satisfying the demands during the next four months?

b If the cost of producing a sailboat with regular-time labor during month 1 were $420, what would be the new optimal solution?

c Suppose a new customer is willing to pay $425 for a sailboat. If his demand must be met during month 1, should Sailco fill the order? How about if his demand must be met during month 4?
