8. A company makes three products, A, B, and C. There are 500 pounds of raw material available. Each unit of product A requires 2 pounds of raw material, each unit of product B requires 2 pounds of raw material, and each unit of product C requires 3 pounds of raw material. The assembly line has 1,000 hours of operation available. Each unit of product A requires 4 hours of assembly, while each unit of products B and C requires 5 hours. The company realizes a profit of $500 for each unit of product A, $600 for each unit of product B, and $1,000 for each unit of product C. How many units of each of the products should the company make to maximize the profit? DO NOT SOLVE THIS PROBLEM. JUST SET UP THE PROBLEM AND WRITE THE INITIAL TABLEAU WITH THE SLACK VARIABLES.

1. Find:
Product = [■(1 * 4+3 * 0&1*3+3*1@2*4+ -1*0&2*3+ -1*1)]= [■(4&6@8&5)]
2. Find the inverse of:
The determinant of the given matrix is 2(-2) - (-1)3 = -4 + 3 = -1
Adjoint of the given matrix is [■(-2&-3@1&2)]
Inverse of the given matrix = Adjoint / Determinant = [■(-2&-3@1&2)] / -1 = [■(2&3@-1&-2)]
3. Compute the transpose of A =
Transpose is [■(2&1@3&-1@0&5)]
