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:
$68,600
Explanation:
An predetermined overhead of $70,000 was estimated for an activity of 2,500 hours. The actual overhead assigned to the products is given by multiplying the fraction of the total 2,500 hours of activity utilized by the products by the predetermined overhead:
The total amount of overhead assigned to the products is $68,600.
