a. Explanation Given: The company manufactures cold steel and stainless steel. The table gives the production capacity of each of the factories and the number of units to fill the order. Calculation: Let x denote the number of days of production at Pottstown and y represent the number of days of production at Ethica factories. The number of units of Cold steel produced per day at Pottstown and Ethica is 20 and 40 respectively. The required order is at least 1600. The statement can be written as an inequality, 20 x + 40 y ≥ 1600 . Similarly, the inequality that represents the number of production of Stainless steel is 60 x + 40 y ≥ 2400 . Since the number of days is positive, the value x ≥ 0 and y ≥ 0 . Therefore, the inequality that describes the requirement is { 20 x + 40 y ≥ 1600 60 x + 40 y ≥ 2400 x ≥ 0 , y ≥ 0 . Solve the equations in terms of y . 20 x + 40 y ≥ 1600 40 y ≥ 1600 − 20 x y ≥ 1600 − 20 x 40 Also, 60 x + 40 y ≥ 2400 40 y ≥ 2400 − 60 x y ≥ 2400 − 60 x 40 Thus, the inequalities can be rewritten as, { y ≥ 1600 − 20 x 40 y ≥ 2400 − 60 x 40 x ≥ 0 , y ≥ 0 (1) The daily cost of operation at Pottstown and Ethica are $20,000 and $24,000 respectively. Thus, the objective function to be minimized is f = 20000 x + 24000 y . Sketch the graph of the inequalities (1) and identify the corners of the region. The boundary equations of the above inequalities are, { y = 1600 − 20 x 40 y = 2400 − 60 x 40 x = 0 , y = 0 (2) Sketch the graph of the straight lines y = 1600 − 20 x 40 , y = 2400 − 60 x 40 , x = 0 and y = 0 as shown below in Figure 1. From Figure 1, it is observed that the equation (2) divides the plane into 4 parts. The solution region of the given inequality set is obtained as follows. Take any arbitrary test point in the region I, to test the solution region of the equation (1). Let ( 10 , 0 ) be the test point of the region I. Substitute x = 10 and y = 0 in the equation (1), { y ≥ 1600 − 20 x 40 y ≥ 2400 − 60 x 40 x ≥ 0 , y ≥ 0 = { 0 ≥ 1600 − 20 ( 10 ) 40 0 ≥ 2400 − 60 ( 10 ) 40 x ≥ 0 , y ≥ 0 That is, the above simplified inequality is { 0 ≥ 35 0 ≥ 45 x ≥ 0 , y ≥ 0 Since the expression 0 ≥ 35 and 0 ≥ 45 is not true, the point ( 10 , 0 ) does not satisfy the equation (1). Thus, the region I is not the solution region of the equation (1). Take any arbitrary test point in the region II, to test the solution region of the equation (1). Let ( 0 , 50 ) be the test point of the region I. Substitute x = 0 and y = 50 in the equation (1), { y ≥ 1600 − 20 x 40 y ≥ 2400 − 60 x 40 x ≥ 0 , y ≥ 0 = { 50 ≥ 1600 − 20 ( 0 ) 40 50 ≥ 2400 − 60 ( 0 ) 40 0 ≥ 0 , 50 ≥ 0 That is, the above simplified inequality is { 50 ≥ 40 50 ≥ 60 0 ≥ 0 , 50 ≥ 0 Since the expression 50 ≥ 6 0 is not true, the point ( 0 , 50 ) does not satisfies the equation (1). Thus, the region II is not the solution region of the equation (1). Take any arbitrary test point in the region III to test the solution region of the equation (1). Let ( 50 , 0 ) be the test point of the region III. Substitute x = 50 and y = 0 in the equation (1), { y ≥ 1600 − 20 x 40 y ≥ 2400 − 60 x 40 x ≥ 0 , y ≥ 0 = { 0 ≥ 1600 − 20 ( 50 ) 40 0 ≥ 2400 − 60 ( 50 ) 40 50 ≥ 0 , 0 ≥ 0 That is, the above simplified inequality is { 0 ≥ 15 0 ≥ − 15 50 ≥ 0 , 0 ≥ 0 Since the expression 0 ≥ 15 is not true, the point ( 50 , 0 ) does not satisfy the equation (1) b.
