Question 1 i) Unknowns x = number of lamps L1 y = number of lamps L2 ii) Function f(x, y) = 15x + 10y iii) Conversion of time from minutes to hours 20 min = 1/3 h 30 min = 1/2 h 10 min = 1/6 h L1 L2 Time(h) Manual 1/3 1/2 100 Machine 1/3 1/6 80 iv) Constraints as a system of inequalities 1/3x + 1/2y ≤ 100 1/3x + 1/6y ≤ 80 x ≥ 0 y ≥ 0 v) Solutions that graphically represent the constraints As x ≥ 0 and y ≥ 0, it lies on the first quadrant 1/3 x + 1/2 y ≤ 100 1/3 • 0 + 1/2 • 0 ≤ 100 1/3 • 0 + 1/6 • 0 ≤ 80 The area of intersection would be the solution to the system of inequalities. vi) Coordinates of the vertices 1/3x + 1/2y = 100; x = 0 (0, 200) 1/3x + 1/6y = 80; y = 0(240, 0) 1/3x + 1/2y = 100; 1/3x + 1/6y = 80(210, 60) vii) …show more content…

f(x, y) = 15x + 10y f(0, 200) = 15•0 + 10•200 = $2,000 f(240, 0 ) = 15•240 + 10•0 = $3,600 f(210, 60) = 15•210 + 10•60 = $3,750 The best solution is to manufacture 210 units of model L1 and 60 units of model L2 to obtain the maximum benefit of
