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.
In this instance, Xavier and Shawn are general partners. In this arrangement, all partners are equally responsible for the business, meaning they are both liable for any financial loss. LLC would protect their personal assets from this type of claim. Obviously, this isn't a sole proprietorship because there is more than one owner.
U.S. President Donald Trump checked one more item on his “To Undo” list of Obama administration actions last Friday when he reset the U.S. policy on Cuba. While the new policy restricts individual tourist travel and business investment in more than half of Cuban industry, it retains many smaller features like permitting family-related travel and professional/academic visits to the country. Among the immediate casualties will be a burgeoning tourism and hospitality industry that sprung up in Cuba after Barack Obama’s friendly overtures began two years ago.

Answer:
Horizontal Management
Explanation:
Horizontal management is an organization structure in which there are very few managers, in this type of management authority is given to the employees. This makes the employees to have a sense of empowerment because they can make vital decisions without the approval of a manager.
In horizontal management, decision making happens rapidly with little or no bureaucracy. These companies tend to have a limited amount of projects on which they work, which benefits from the unstructured, open environment since the entire team communicates and share essential information on where the project is and where it is heading to.
