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 Net Cash <em>used</em> in Financing activities is $30,800
Explanation:
<em>Step 1 Determine the Movement in Cash during the period.</em>
Movement = Ending Cash Balance - Beginning Cash Balance \
= 18,200 - 11,600
= 6,600 (inflow)
<em>Step 2 Determine the Cash flow in Financing Activities </em>
<u>Cash flow statement for the year</u>
Cash flow from Operating Activities $29,000
Net Cash flow from Investing Activities $ 8,400
Net Cash flow from Financing Activities (Balancing figure) ($30,800)
Movement in Cash during the year $6,600
Therefore, The Net Cash used in Financing activities is $30,800
I think it can be the "D"
Answer:
The correct answer is A
Explanation:
ERP termed as or stands for Enterprise Resource Planning, which is defined as the centralized system, that provides the integration with the enterprise functions be it analytics, planning, sales, finance, HR, customer relations and procurement as well other application functions which are connected.
So, this system consider the benefit of enabling the company to use the single database system, which is centralized and thus remove the duplicate data entries.
