For the Dakota problem:

1 Find and interpret the shadow prices 2 If 18 finishing hours were available, what would be Dakota’s revenue? (It can be shown by the methods of Section 6.3 that if 16  finishing hours  24, the current basis remains optimal.)

3 If 9 carpentry hours were available, what would be Dakota’s revenue? (For 20/3

  carpentry hours <= 10, the current basis remains optimal.)

4 If 30 board feet of lumber were available, what would be Dakota’s revenue? (For 24  lumber  , the current basis remains optimal.)
5 If 30 carpentry hours were available, why couldn’t the shadow price for the carpentry constraint be used to determine the new z-value?
