I post this question but C, G, and H was not answered...can I have an answer for them please as soon as possible.
c.
Dual price for second constraint is 2.333.
It means for every additional unit of increase/decrease of 2nd constraint, objective value will increase/decrease by 2.333
G.
Yes, this problem can be solved using graphical model. Additional constraints required are non-negativity constraints => X1 >= 0,X2>= 0 and X3>= 0
H.
Objective function value represents the value of the objective function after substituting X1,X2 and X3
Objective function value => 25X1+30X2+15X3 where X1 = 140, X2 = 0 and X3 = 80
so, Objective function value => 25*140 + 30*0 + 15*80 =
4700

The LP problem whose output follows determines how many necklaces, bracelets, rings, and earrings a jewelry store should stock. The objective function measures profit; it is assumed that every piece stocked will be sold.Constraint 1 measures display space in units, constraint 2 measures time to set up the display in minutes. Constraints 3 and 4 are marketing restrictions. using excel solver: To what value can the profit on ring increases before the solution would change?

Your problem will have exactly two variables (an X1 and an X2) and will incorporate a maximization (either profit or revenue) objective. You will include at least four constraints (not including the X1 ≥ 0 and X2 ≥ 0 [i.e., the “Non-negativity” or “Duh!”] constraints). At least one of these four must be a “≤” constraint, and at least one other must be a “≥” constraint; do not include any “= only” constraints. You must have a unique Optimal Solution...

One costs $14,000 per batch, requires 3 tons of one major ingredient and 1 ton of the other, and yields 2 tons of output product. The second process costs $30,000 per batch, requires 2 and 7 tons of the ingredients, respectively, and yields 5 tons of product. The third process costs $11,000 per batch, requires 9 and 2 tons of the...
