Explanation Let x and y represents the number of square feet of window space and wall space, respectively. In a small town in south Carolina, zoning rules require that the window space in a house be at least one-sixth of the space by solid walls. That is x ≥ 1 6 y . The cost to build windows and solid are $10 per ft 2 and $20 per ft 2 respectively and the total amount available for building walls and windows is no more than $12,000. That is, 10 x + 20 y ≤ 12 , 000 . The monthly estimated cost to heat the house is $10 for each square foot of windows and the $0.20 for each square foot of solid walls and available to pay for heat is no more than $160 per month. That is, 0.32 x + 0.20 y ≤ 160 From the above information, the linear programing problem can be stated as follows, Maximize z = x + y Subject to the constraints, x ≥ 1 6 y (1) 10 x + 20 y ≤ 12 , 000 (2) 0.32 x + 0.20 y ≤ 160 (3) x ≥ 0 y ≥ 0 Consider the equation (1). Rewrite the given equation, x − 1 6 y ≥ 0 . The given inequality in the equation is ≥ . Therefore, the solid line is used to join the coordinates of this equation. Now, replace the symbol ≥ by the symbol = in given equation (1). Then the equation (1) becomes, x − 1 6 y = 0 . Obtain any 2 coordinates of the above equation to plot on the line. Consider x = 0 and obtain the corresponding values of y respectively. Substitute x = 0 in the linear equation x − 1 6 y = 0 . 0 − 1 6 y = 0 − 1 6 y = 0 y = 0 Thus, the value of y is 0 at x = 0 . Hence, the first coordinate is ( 0 , 0 ) . Consider the point x = 1 , y = 6 . Substitute x = 1 , y = 6 in the linear equation x − 1 6 y = 0 . 1 − 1 6 ( 6 ) = 0 1 − 1 = 0 0 = 0 Hence, the second coordinate is ( 1 , 6 ) . Therefore, the coordinates are ( 0 , 0 ) and ( 1 , 6 ) . Use the test point to determine the half plane which is to be shaded. For x ≥ 1 6 y , the test point be ( 1 , 1 ) . Now substitute the test point ( 1 , 1 ) in x − 1 6 y ≥ 0 . 1 − 1 6 ( 1 ) ≥ 0 6 − 1 6 ≥ 0 5 6 ≥ 0 It is noticed that the inequality x − 1 6 y ≥ 0 is true. Thus, shade the half-plane that contain the test point ( 1 , 1 ) . That is, the half plane below the line. Consider the equation (2). The given inequality in the equation is ≤ . Therefore, the solid line is used to join the coordinates of this equation. Now, replace the symbol ≤ by the symbol = in given equation (2). Then the equation (2) becomes, 10 x + 20 y = 12 , 000 . Obtain any 2 coordinates of the above equation to plot on the line. Consider x = 0 , 1200 and obtain the corresponding values of y respectively. Substitute x = 0 in the linear equation 10 x + 20 y = 12 , 000 . 10 ( 0 ) + 20 y = 12 , 000 20 y = 12 , 000 y = 12 , 000 20 y = 600 Thus, the value of y is 600 at x = 0 . Hence, the first coordinate is ( 0 , 600 ) . Substitute x = 1200 in the linear equation 10 x + 20 y = 12 , 000 . 10 ( 1200 ) + 20 y = 12 , 000 1200 + 20 y = 12000 20 y = 12000 − 12000 y = 0 Hence, the second coordinate is ( 1200 , 0 )
