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.
The answer is option B. The main challenge of career planning in changing times is that you need to revise your plans often.
The world we live in is dynamic. New inventions, new technology, new methods of doing things always come up with time.
Because of this, when making a career plan, one must be fully aware that the process is not static. That is, changes would occur and as such, you have to revise your plans often so that it is in line with what is obtainable at the time.

After one year you will be able to get 305 extra dollars then what you have put in hope this helps you
Answer:
$21.42
Explanation:
The computation of fixed component in the predetermined overhead rate is shown below:-
Fixed component in the predetermined overhead rate = Fixed Overhead ÷ Machine Hours
= $87,822 ÷ 4,100
= $21.42
Therefore for computing the fixed component in the predetermined overhead rate we simply divide the fixed overhead by machine hours.
And all the other information i.e given is not relevant. Hence, ignored it
