Question 14

Determine whether the statement is true or false. If it is true, explain why it is true. If it is false, give an example to show why it is false. The following problem is a linear programming problem.
Minimize   subject to:  x - y = 0

Accepted Answer

A)  False.
As we know, a linear programming problem consists of a linear objective function to be maximized or minimized subject to certain constraints in the form of linear equalities or inequalities. The linear objective function to be minimized is C = 4x + 5y , but the constraint  are not in the form of linear inequality. 
B)  True.

Question 15

Custom Office Furniture Company is introducing a new line of executive desks made from a specially selected grade of walnut. Initially, three different models-A, B, and C-are to be marketed. Each model A desk requires  hr for fabrication, 1 hr for assembly, and 1 hr for finishing; each model B desk requires  hr for fabrication, 1 hr for assembly, and 1 hr for finishing; each model C desk requires  hr,  hr, and  hr for fabrication, assembly, and finishing, respectively. The profit on each model A desk is $26, the profit on each model B desk is $28, and the profit on each model C desk is $24. The total time available in the fabrication department, the assembly department, and the finishing department in the first month of production is 240 hr, 160 hr, and 150 hr, respectively. To maximize Custom's profit, how many desks of each model should be made in the month?

Question 18

Patricia has at most $36,000 to invest in securities in the form of corporate stocks. She has narrowed her choices to two groups of stocks: growth stocks that she assumes will yield a 11% return (dividends and capital appreciation) within a year and speculative stocks that she assumes will yield a 22% return (mainly in capital appreciation) within a year. Determine how much she should invest in each group of stocks in order to maximize the return on her investments within a year if she has decided to invest at least 3 times as much in growth stocks as in speculative stocks.

Question 20

Formulate but do not solve the following exercise as a linear programming problem. Kane Manufacturing has a division that produces two models of fireplace grates, model A and model B. To produce each model A grate requires 4 lb of cast iron and 6 min of labor. To produce each model B grate requires 5 lb of cast iron and 3 min of labor. The profit for each model A grate is $2.00, and the profit for each model B grate is $1.50. If 1,100 lb of cast iron and 20 hr of labor are available for the production of grates per day, how many grates of each model should the division produce per day in order to maximize Kane's profits?
