19,500 minutes per day for assembly and finishing. The
profit on each pair of style 891 is $18.00, and the profit
on each pair of style 917 is $22.50. How many pairs of
cach style should be produced per day to obtain maxi-
mum profit? Find the maximum daily profit.

36, refer to the farm co-op application in Example 2(a).
Rework that linear programming problem with the indi-
cated changes in one constraint and answer the questions.
35. (a) If one more acre of land became available (for a
total of 6001 acres), how would this change the
co-op's planting strategy and its maximum profit?
(b) Repeat part (a) if 8 more acres of land were
available.
(c) Based on parts (a) and (b), what is the profit value
of each additional acre of land? This value is called
the shadow price of an acre of land.
36. (a) If one more gallon of fertilizer/herbicide became
available (for a total of 40,501 gallons), how would
this change the co-op's planting strategy and its
maximum profit?
(b) Repeat part (a) if 8 more gallons of fertilizer/herbi-
cide were available.
