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:
Inquiry Letter
Sometimes a business can send this to a supplier to find out if they have a certain good in stock.
Purchase Requisition
This is a document used by a department in a company to request that those in charge of procurement acquire some goods for them.
Quotation
This is a document sent by a supplier to the prospective buyer informing them of the goods they have and their selling price.
Purchase Order
This is the document that shows a formal request for goods from a supplier.
Delivery Note
This is used to confirm that the buyer has received the goods they ordered. The buyer will typically sign this document to confirm receipt.
Invoice
A supplier prepares and sends this to the buyer to show them the goods they ordered and the prices so that the buyer knows how much they owe.
Answer:
a. less wealthy and they buy less.
Explanation:
we are assuming a situation where the price level rises (inflation rises), so anyone holding cash will be able to purchase a smaller amount of goods with the same amount of cash simply because the goods are more expensive. E.g. you purchased 10 goods with $100, but if the inflation rate increases to 10%, you will be able to purchase only 9 goods with the same $100. As inflation rises, people holding cash (or other monetary form) will lose wealth and purchasing power.

Answer:
Equivalent units of Production = 46500 & 37800
Explanation:
At the start of October, Clonex Labs inc, started with 385000 units into production and at the end of the month it had completed 409000 units this means the difference between 409000 and 385000 is the number of units transferred to the next department (i.e 24000), now that we have computed this, we find ending work-in-process as follows:
Clonex Labs, Inc. Materials Conversion
Units transferred to the next department: 24000 24,000
Ending work in process :
Materials : 30000x75% 22500
Conversion : 30000x46% 13800
------------- -------------
Equivalent units of Production = 46500 37800
