Answer:

Operate mine 1 four 4 days and mine 2 during 6 days to obtain minimum cost for the desired output of 850 gold and 18,000 silver

Explanation:

We generate the equation system on excel:

(50g + 3000s) Q_1 --> output generated on Mine 1

(75g + 1,000s) Q_2 --> output generated on Mine 2

12,000 Q1 + 17,000 Q2 = cost of the mines

we do solver to minimize the days of each mine considering a desired output of 18,000 silver and 650 gold:

and get the following:

M1  4 days  output: (50g + 3000s) 4 = 200 g    12,000s

M2 6 days  output: (75g + 1,000s) 6 =  450g      6,000s

Cost: 12,000 x 4 + 17,000 x 6 = 150,000

Residential Investment Payments of Factor Income to the rest of the world National Income Inventory Adjustment 0.00 Personal Con
Ivanshal [37]

Please find full question attached

Answer and Explanation:

Gross domestic product is calculated:

Gross Domestic Product(GDP) = Gross National Product (GNP)  - Receipts of factor income from rest of the world + Payments of factor income to the rest of the world

So to find GDP, we calculate GNP

GNP = NNP+Depreciation

To calculate GNP, we calculate NNP:

Net national product (NNP) =national income, so we have,

NNP = $2,445 billion

GNP = NNP + Depreciation = $2,445+$75

GNP = $2,520 billion

So we substitute in GDP formula to calculate GDP

GDP = 2,520 - 70 + 50 = $2500 billion

GDP = $2,500 billion

Government consumption and gross investment= Government transfer payments + Non-residential investments

Government consumption and gross investment is given by G

G = 200+250 = $450 billion

G = $450 billion

lilavasa [31]

Answer:

The correct answer is letter "A": magnified, reduced.

Explanation:

Scarcity does not only represent individuals having to sacrifice some of their needs to fulfill others because resources are limited. Scarcity can also represent the reason for dispute between social levels. When resources are scarce and one social stratum has more access to it, differences will increase. The opposite happens when the resources are allocated properly between them: differences are likely to be reduced.

Rudiy27

Answer:

the  price elasticity of supply is 0.555

Explanation:

The computation of the price elasticity of supply is given below:

= Percentage change in quantity supplied ÷ percentage change in price

= (25 - 20) ÷ (25 + 20) ÷ 2 ÷ (750 - 500) ÷ (750 + 500) ÷ 2

= 5 ÷45 ÷ 250 ÷ 125

= 0.555
