Please answer both 1 and 2. For the simplex method, please use a Simplex Tableau and show intermediate steps.

A company makes product 1 and product 2 from two resources. The linear programming model for determining the amounts of product 1 and 2 to produce (x1 and x2) is maximizeZ=8x1+2x2(profit,$)subjectto4x1+5x22x1+6x2x1,x220(resource1,lb.)18(resource2,lb.)0 1.
