1 . If Electrocomp decides that at least 20 air conditioners should be produced but no more than 80 fans should be produced , the optimal production mix of air conditioners and fans is __________. ( The first number is for air conditioners and the second for fans .)
2 . In the optimal solution for the above question ( Question 1 ), the slack for the four constrains — Total hours of wiring , Total hours of drilling , Number of air conditioners , Number of fans are __________, respectively . ( Hint : A negative number shows that the constraint is binding downward , i . e . it sets a lower rather than an upper limit . You may take the negative sign out when interpreting the results .)
3 . If Electrocomp decides that at least 30 air conditioners should be produced but no more than 50 fans should be produced , the optimal production of air conditioners is __ and the optimal production of fans is _. ( Please only enter an integer and include no units .)
4 . In the optimal solution for the above question ( Question 3 ), the slack for the four constrains — Total hours of wiring , Total hours of drilling , Number of air conditioners , Number of fans are __________, respectively . ( Hint : A negative number shows that the constraint is binding downward , i . e . it sets a lower rather than an upper limit . You may take the negative sign out when interpreting the results .)
5 . The optimal production of benches is __ and the optimal production of tables is __. ( Please only enter an integer and include no units . Hint : Because of the resource constraints , you may not be able to produce 4 tables even if the solution is 3.8 ; you may have to just produce 3 tables .)
6 . The optimal dollar amount invested in Petrochemical stock is _________ dollars , and the optimal dollar amount invested in Utility stock is ___________ dollars . ( Please only enter an integer and include no units . Hint : The total risk on each stock is the risk index times the
