7 Consider the Sailco problem (Example 12 in Chapter 3).

Suppose we want to consider how profit will be affected if we change the number of sailboats that can be produced each month with regular-time labor. How can we use the PARA command to answer this question? (Hint: Let c  change in number of sailboats that can be produced each month with regular-time labor. Change the right-hand side of some constraints to 40 c and add another constraint to the problem.)
