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.

Explanation:
The annual premium that would result in Stephanie's annual out-of-pocket expense that is about the same as her current plan is <em>b. $0. 28 per $100 of value.</em>
Data and Calculations:
Home value = $355,000
Annual premium rate = $0.42 per $100
Deductible $500
Total annual out-of-pocket expense = $1,991 ($355,000 x 0.0042 + $500)
New deductible = $1,000
New annual premium rate = $0.28
Total annual out-pocket expense based on the new premium rate = $1,994 ($355,000 x 0.0028 + $1,000)
Thus, the annual premium that would result in Stephanie's annual out-of-pocket expense that is about the same as her current plan is <em>Option b.</em>

Answer:
A) True
Explanation:
The Balance Sheet is a snapshot of the financial situation of a company at the end of the accountable period. It shows which productive resources (assets) the company has for the development of its activities and how they are financed. Assets can be financed by external (Obligation with creditors – Liabilities) or internal sources (Issuing equity shares - Shareholders' equity). As every Asset must be financed either or both with Liabilities or Shareholders' equity, in the Balance Sheet, the accountable equation is represented.
