MinZ=x1+x2+x3+x4+x5+x6+x7 Your answer(s) should be in the form of expression(s). s.t. Monday x1+x4+x5+x6+x775 Monday x1+x4+x5+x6+x775 Check which variable(s) should be in your answer. Tuesday x1+x2+x5+x6+x730 Check which variable(s) should be in your answer. Wednesday x1+x2+x3+x6+x725 Check which variable(s) should be in your answer. Thursday x1+x2+x3+x4+x750 Check which variable(s) should be in your answer. Friday x1+x2+x3+x4+x580 Check which variable(s) should be in your answer. Saturday x2+x3+x4+x5+x675 Check which variable(s) should be in your answer. Sunday x3+x4+x5+x6+x755 Check which variable(s) should be in your answer. x1,x2,x3,x4,x5,x6,x70 Find the optimal solution. (x1,x2,x3,x4,x5,x6,x7)=() Give the number of call-center employees that exceed the minimum required. (M,Tu,W,Th,F,Sa,Su)=
