Mining scenario A mining company owns two mines, each of which produces three grades (high, medium, and low) of ore. The company

has a contract to supply a smelting company with at least 12 tons of highgrade ore, at least 8 tons of medium-grade ore, and at least 24 tons of low-grade ore. Each hour of operation, mine 1 produces 6 tons of high- grade ore, 2 tons of medium-grade ore, and 4 tons of low-grade ore. Each hour of operation, mine 2 produces 2 tons of high-grade ore, 2 tons of medium-grade ore, and 12 tons of low-grade ore. It costs $200 per hour to operate mine 1 and $160 per hour to operate mine 2. How many hours should each mine be operated so as to meet the contractual obligations at the lowest total operating cost

Answer:

the lowest operating cost is achieved when mine 1 is operated for 0 hours and mine 2 is operated for 2 hours.

Explanation:

Mining hours of mine 1: M1

mining hours of mine 2: M2

Objective function: Minimize operating cost < 200M1 + 160 M2

Explicit constraints:

6M1 + 2M2 ≥ 12

2M1+ 2M2≥ 8

4M1+ 12M2 ≥ 24

Implicit constraints:

M1> 0

M2>0

See the attachment for feasible region

The coordinates of feasible region are (0,0), (2,0),(0,2),(1.5,1.5)

To maximize cost substitute each of these coordinates in objective function

for(0,0)

cost=0 (neglect this cost since M1>0 and M2 >0)

for(2,0)

cost= 320

for (0,2)

cost= 400

for (1.5,1.5)

cost= 540

the lowest operating cost is achieved when mine 1 is operated for 0 hours and mine 2 is operated for 2 hours

A resource having economic worth that a person, business, or nation possesses or controls with the hope that it would someday be useful is referred to as an asset. The balance sheet of a business lists assets. They are divided into four categories: tangible, financial, fixed, and current. They are acquired or produced in order to raise a company's worth or improve the operations of the company. Whether it's industrial equipment or a patent, an asset may be viewed of as anything that, in the future, can create cash flow, lower expenditures, or increase sales. A resource having economic worth that a person, business, or nation possesses or controls with the hope that it would someday be useful is referred to as an asset.

Cost Flow Relationships
Lady_Fox [76]

Answer:

(A) Cost of goods sold=$7,175,000

(B) Direct material cost= $3,655,000

(C) Direct labor cost= $2,825,000

Explanation:

(A) The cost of goods sold can be calculated as follows

Cost of goods sold= Sales-gross profit

Sales= $12,375,000

Gross profit= $5,200,000

Cost of goods sold= $12,375,000-$5,200,000

= $7,175,000

(B) The direct materials cost can be calculated as follows

Direct cost of materials= materials purchased-indirect materials-materials inventory

Materials purchased= 4,125,000

Indirect materials= 180,000

Materials inventory= 290,000

Direct materials cost= 4,125,000-180,000-290,000

= $3,655,000

(C) The direct labor costs can be calculated as follows

Direct labor costs= Total manufacturing cost for the specified period-direct materials-factory overhead

Total manufacturing costs= 7,880,000

Direct materials= 3,655,000

Factory overhead= indirect labor+indirect materials+other factory overhead

= 410,000+180,000+810,000

= 1,400,000

Direct labor costs= 7,880,000-3,655,000-1,400,000

= $2,825,000

Rachel entered into a contract to purchase a 2004 Dodge from Hanna, who lived in the neighboring apartment. When a dispute arose
Genrish500 [490]

Answer:

Hanna is correct.

Explanation:

The sale of the 2004 Dodge cannot be construed to be a sale of goods under the Uniform Commercial Code since this law covers sales of goods by merchants.  Hanna cannot be said to be a merchant of 2004 Dodge as she is not known to be in the business for the purchase and sale of cars.  Therefore, the case should be adjudicated under the common law.  What has taken place in this instance is the exchange of a personal asset.  Hanna cannot make a trading profit from the sale, but a capital gain.  Rachel is not correct.
