Answer:
They should operate Mine 1 for 1 hour and Mine 2 for 3 hours to meet the contractual obligations and minimize cost.
Explanation:
The formulation of the linear programming is:
Objective function:
Restrictions:
- High-grade ore:
- Medium-grade ore:
- Low-grade ore:
- No negative hours:
We start graphing the restrictions in a M1-M2 plane.
In the figure attached, we have the feasible region, where all the restrictions are validated, and the four points of intersection of 2 restrictions.
In one of this four points lies the minimum cost.
Graphically, we can graph the cost function over this feasible region, with different cost levels. When the line cost intersects one of the four points with the lowest level of cost, this is the optimum combination.
(NOTE: it is best to start with a low guessing of the cost and going up until it reaches one point in the feasible region).
The solution is for the point (M1=1, M2=3), with a cost of C=$680.
The cost function graph is attached.
Answer:
The answer is "$400"
Explanation:
The price value of the exercise:
= $127
The expiration date price value is:
= $135
Calculating the profit for Calls buyer:
= $135-$127
= $8
The value of 1 call = 100 shares
calculating the total profit :
=$ 8 × 100
= $ 800
One alternative purchase price:
= $12
Call option Total purchase price:
= $12 × 100
= $1200
The buyer's total loss:
= $1200 - $800
= $400
The Loss for the buyer:
Hence profit for the writer = $400
