Can someone please help me figure out this question? I am so confused...

Solve this linear programming problem using the simplex method. Maximize P = 80x + 40y subject to these constraints: 10x + 10y s 215 20x + 15y s 350 40x + 15y s 490 50x + 10y s 575 20x + 35y s 700 50x + 5y s 500 x 2 0, y 2 O The maximum value for P = 1120 v This value of P occurs when x = 7 y and y = 14 y If u1, u2, u3, u4, US, and u6 represent the slack variables in the six counstraints (u1 the slack variable in the top constraint listed above, u2 for the second, etc.), then give the values for each of the four slack variables when the optimal solution is reached: u1= u2=0 I: D) || 0 xxx\\'x
