3. Solve the following problems on the computer, you can confirm your answers graphically but this is not necessary. Report the solution which includes the decision varies, disposal variables, and the cost (include units). Min z = 1X1 + 4X2 ST: Nut A: 10X1 + 10X2 = 40 Nut B 1X1 + 0X2 2 5 Nut C: OX1 + 1X2 2 6 X1, X2 2 0 b. Plot on the graph below. Let X2 be the y-axis and X1 be the x-axis. O 2 4 6 8c. (This problem in similar except the last two rows have been changed by changing the last two RHS.) Min z = 1X1 + 4X2 ST: Nut A: 10X1 + 10X2 = 40 Nut B: 1X1 + 0X2 2 2 Nut C: OX1 + 1X2 2 1 X1, X2 2 0 d. Plot on the graph below. Let X2 be the y-axis and X, be the x-axis. O 2 4 6 8
