There are 3 factories on the Momiss River. Each emits 2 types of pollutants, labeled P1 and P2, into the river. If the waste fro

m each factory is processed, the pollution in the river can be reduced. It costs $1500 to process a ton of factory 1 waste, and each ton processed reduces the amount of P1 by 0.10 ton and the amount of P2 by 0.45 ton. It costs $1000 to process a ton of factory 2 waste, and each ton processed reduces the amount of P1 by 0.20 ton and the amount of P2 by 0.25 ton. It costs $2000 to process a ton of factory 3 waste, and each ton processed reduces the amount of P1 by 0.40 ton and the amount of P2 by 0.30 ton. The state wants to reduce the amount of P1 in the river by at least 30 tons and the amount of P2 by at least 40 tons.
Required:

Answer:

Kindly check explanation

Explanation:

Using table for our evaluation :

____________POLLUTANT

Factories___P1 ______P2 ____COST

__1_______0.1______ 0.45 ___ 1500

__2______ 0.2 _____ 0.25 ____1000

__3 ______0.40 ____ 0.30 ____2000

_________ ≥ 30 ____ ≥ 40 _____ z

Let amount of waste produced by Factories 1, 2 and 3 equal f1, f2 and f3 respectively.

Linear Program that will minimize the cost of reducing pollution by the desired amounts

Min cost:

min z = 1500f1 + 1000f2 + 2000f3

0.1f1 + 0.2f2 + 0.4f3 ≥ 30

0.45f1 + 0.25f2 + 0.3f3 ≥ 40

f1, f2, f3 ≥ 0

Volgvan

Answer: $8600

Explanation:

Joint cost allocation:

Product :

Loin chops

Pounds - 3000

Price per pound - $5

ground

Pounds - 10,000

Price per pound - 2.00

ribs

Pounds - 4,000

Price per pound - 4.75

bacon

Pounds - 6,000

Price per pound - 3.50

total joint cost - $43000

Sales cost per product :

Loin chops - 3000 × 5 = $15,000

Ground = 10000 × $2 = $20,000

Ribs - 4000 × $4.75 = $19,000

Bacon - 6000 × $3.50 = $21,000

Loin cost allocation is given by :

Total joint cost × (sales value of Loin chops ÷ Total sales value of all products)

$43,000 × ($15,000 ÷ $(15,000 + 20,000 + 19,000 + 21,000))

$43,000 × ( $15000 ÷ $75000)

$43,000 × 0.2 = $8600

Choose the statement that is incorrect.
MAVERICK [17]

Answer:

B. In the long​ run, a change in the nominal exchange rate brings an equivalent change in the real exchange rate.

Explanation:

As we know that in the short run there is a decline in the nominal exchange that results in a decrease of real exchange rate due to which there is a reduction of the import and the export is risen.

But in the case of the long run, if there is a change in the nominal exchange rate so the real exchange rate would remain the same

This results that if there is a change in the nominal exchange rate so it would not bring the equal change in the real exchange rate

Hence, option B is incorrect
