Answer:

Water has a much higher refractive index, so does the material that the animals are made of so you can really make that difference in how light moves through the materials very minimal; therefore you can't see them. Even a piece of glass underwater is very difficult to see because that glare just doesn't happen.

Allushta [10]

Let us see it from a cost-efficiency point of view. We have that every unit of the first selles costs 40$. But the total cost might be higher, since there is a chance for defect. On average, on 3% of the cases the defect will happen and it will cost him 500$. Hence, on average, a fence unit from producer a costs 40$ and has a repair cost of 3%*500$=15$. The total thus is 55$. For the second provider of fences, the standard cost is 50$. Similarly, the average repair cost is 0,5%*500$=2,5$. Hence, the total cost per unit is 52,5$ (total cost=upfront payment+repair costs). We see thus that the lady should win the bid; even if you pay more upfront, the difference in durability makes up the cost difference.

Given the formula for future growing annuity

we need to solve for the yearly payment:

grow rate: 0.04

annual effective rate: 8% compounding semiannually:

$(/1+0.08/2)^2-1 = r_e\\$

r= 0.0816

FV 2,500,000

n 46

Formula for future value fo an ordinary annuity:

$C_0 \times \frac{(1+r)^n-(1+g)^n}{r-g} = FV$

$C_0 \times \frac{(1+0.0816)^{46}-(1+0.04)^{46}}{0.0816-0.04} = 2,500,000\\C_0 = $3,373.4855$

The first annual depoisit will be of 3,373.49 dollars

At the end of April, Cavy Company had completed Job 766 and 765. According to the individual job cost sheets the information is

IceJOKER [234]

Answer:

Instructions are below.

Explanation:

Giving the following information:

Job 765:

Direct material= $5,670

Direct labor= $3,500

Machine Hours= 27

Job 766:

Direct material= $8,900

Direct labor= $4,775

Machine Hours= 44

Job 765 produced 152 units, and Job 766 consisted of 250 units.

Assuming that the predetermined overhead rate is applied by using machine hours at a rate of $200 per hour.

Costs sheet:

Job 765:

Direct material= 5,670

Direct labor= 3,500

Allocated overhead= 200*27= 5,400

Total cost= 14,570

Unitary cost= 14,570/152= $95.85

Job 766:

Direct material= 8,900

Direct labor= 4,775

Allocated overhead= 200*44= 8,800

Total cost= 22,475

Unitary cost= 22,475/250= $89.9

The following two graphs show the markets for smartphones in Sweden and Norway. Use the graphs to answer the questions that foll

zalisa [80]

Answer:

Assume there are no transportation costs. With trade, the price of $22.5 brings about balance in exports and imports. At this price, 600 smartphones are traded. With trade, Sweden produces 900 smartphones and consumes 300 smartphones, and Norway produces 300 smartphones and consumes 900 smartphones.

Now suppose the per-unit transportation cost from Sweden to Norway is $5. With trade, the transportation cost changes the price of smartphones in Sweden to $25 and in Norway to $25. Sweden will produce 800 smartphones and consume 400 smartphones, thus exporting 400 smartphones. Norway will produce 400 smartphones and consume 800 smartphones, thus importing 400 smartphones.

Explanation:

With no transportation costs, Sweden shall export smartphones and Norway shall import smartphones because the market price is lower in Sweden than in Norway.

The demand and supply functions for smartphones in Sweden, derived from the given values, are:

$Q_{D} = 1200 - 40P\\$

$Q_{S} = 40P$

The export supply (ES) equation is:

$ES = Q_{S} - Q_{D}$

ES = 40P - (1200 - 40P)

ES = 80P - 1200

The demand and supply functions for smartphones in Norway, derived from the given values, are:

$Q_{D} = 1800 - 40P$

$Q_{S} = 40P - 600$

The import demand (ID) equation is:

$ID = Q_{D} - Q_{S}$

ID = 1800 - 40P - (40P - 600)

ID = 2400 - 80P

The equilibrium price and quantity traded is determined where ES = ID.

80P - 1200 = 2400 - 80P

This simplifies to P = 22.5

Q = 2400 - 80(22.5) = 600

Next, a transaction cost of $5 per unit is imposed from Sweden to Norway. This changes the ES function as follows.

New ES = 80(P - 5) - 1200

New ES = 80P - 1600

The new equilibrium is where New ES = MD.

80P - 1600 = 2400 - 80P

This simplifies to P = 25

Q = 80(25) - 1600 = 400

Jeff deposits $3,000 into an account which pays 5 percent interest, compounded annually. At the same time, Kurt deposits $3,000

VashaNatasha [74]

Answer:

Kurt will have a smaller account value than Jeff will

Explanation:

The formula for calculating future value = A (B / r)

B = [(1 + r)^n] - 1

Jeff : $3000 x [(1.05^3 - 1 ) / 0.05] = $9457.50

Kurt :$3000 x [(1.03^3 - 1 ) / 0.03] = $9272.70

Jeff would have a higher account value than Kurt
