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

telo118 [61]

Answer:

Decrease

Explanation:

Fiscal policy is an important policy tool which is used by the government to account for revenue and expenses. During a boom stage, when the economy is improving the government implements more taxes. Similarly, in a recession period, where economic growth is negative an expansionary discretionary fiscal policy is applied.

Kipish [7]

Answer:

total cost of having the manuscript type is $680

Explanation:

given data

first time = $5 per page

revised = $3 per page

manuscript = 100 pages

revised only once = 40

revised twice = 10

to find out

total cost of having the manuscript typed

solution

we know for 1st time page  cost is

page 1st time = 100 - 40 - 10  = 50 page

cost 1st time = 50 × $5 per page = $250    .................1

and

for first revision

first revision page = 40

cost of first revision = 40 × ( first time $5 + first revision $3 )

cost of first revision = 40 × 8 = $320       ......................2

and

for second revision

second revision page = 10

second revision cost = 10 ×  ( first time $5 + first revision $3 + second revision $3  )

second revision cost = 10 × 11 = $110     ..........................3

add all 3 equation

total = $250  +  $320 + $110

so total cost of having the manuscript type is $680

A minimum wage is an example of a price floor or minimum price that must be paid. If effective, such a price floor would be ____
valkas [14]

Answer:

If effective, such a price floor would be <u>above</u> the market price and would lead to a <u>excess supply</u>.

Explanation:

A price floor can be described as a price control in which the minimum price to be charged for goods and services is imposed by a government or a group.

For a price floor to be effective and binding, it has to be set above the market or equilibrium price. This is because a price floor will neither be effective nor nonbinding when it set below the equilibrium price.

Any price above the equilibrium or market price creates or leads to excess supply. Excess supply is a situation whereby quantiy of commodity supplied is more than the quantity demanded of the commodity.

Based on the above explanation, if effective, such a price floor would be <u>above</u> the market price and would lead to a <u>excess supply</u>.
