Please please answer all the questions, very urgent!! please

(a) How many variables are there? Answer: (b) How many constraints are there? Answer: How long does Product S take to go through Operation A (in hours)? Question 5 Suppose we have 2120 hours available for Operation C, and the manufacturing time for Operation C is 2 hours per unit, regardless of its product type. (Suppose this for other questions that follow.) Then, the correct Operation C constraint is 2s+2t>=2120. A. Main Mall Manufacturing (MMM) Main Mall Manufacturing (MMM) produces two types of products: Product S and Product T. Each of these products goes through a series of operations ( A,B,C and D), requiring specific manufacturing times in these operations. We have limited hours available for each of these four operations. The correct LP formulation (with the objective function and the Operation C constraint missing) is as follows: Main Mall Manufacturing Let s=# Product s Let t=# Product T Max s.t. 4s+1.5t=0,t>=0. (Operation D) Above, the objective function represents the total profit in dollars, and the units associated with the first four constraints are in hours. Suppose we have 2120 hours available for Operation C, and the manufacturing time for Operation C is 2 hours per unit, regardless of its product type. (Suppose this for other questions that follow.) Then, the correct Operation C constraint is 2s+2t>=2120. True False Question 6 2 pts Suppose that the constraints associated with Operation A and Operation D are binding. What is the value of S
