Answer:

D. $100

Explanation:

Given: William install 7 system per day at the cost of $300.

           William install 8 system per day at the total cost of $400.

Remember, If the marginal cost curve is upward-sloping, this means that as output increase, marginal costs will also increase.

Marginal cost is an additional cost incurred in producing additional unit of output.

Now, finding additional payment that eighth customer has to pay.

Change in marginal cost= Cost\ incurred\ in\ installing\ 8\ system - cost\ incurred\ in\ installing\ 7\ system

⇒ Change in marginal cost=  \$400-\$300

∴  Change in marginal cost= \$ 100

Hence, there is an increase in marginal cost by $100 as output increases, therefore, William will install eight sound systems per day only if the eighth customer is willing to pay at least $100.

Natalka [10]

Answer:

Ans. The expected rate of return on the Inferior Goods Co. stock is 5.90%

Explanation:

Hi, you just have to multiply the expected earnings by the probability of occurance of a certain event and then add up all the products. Here is the information all organized to be processed.

Item                  Prob Earn

Booming           20% -6%

Normal           55% 7%

Recession   25% 13%

Ok, now let´s calculate the expected rate of return.

ExpectedReturn=(0.2*(-0.06))+(0.55*0.07)+(0.25*0.13)

ExpectedReturn=-0.012+0.039+0.033=0.059

So the expected rate of return of the stock is 5.90%

Best of luck.

tatuchka [14]

Answer:

A

Explanation:

The quantitative theory of money states that MV=PT.

M: money supply

V: velocity of circulation (number of times that a dollar changes of holder in a period)

P : price of a typical transaction

T: total number of transactions.

We can also write the equation as MV=PY, because the value of transactions is equal to the GDP (Y).

If M has a constant growth but there are fluctuations in V, then P, Y or both change.

You want to be a millionaire when you retire in 40 years. a. How much do you have to save each month if you can earn an annual r
oksano4ka [1.4K]

Answer:

The answers are:

a. 1866.79

b. 2489.05

c. 3733.57

Explanation:

a. Let us begin by calculating the total amount to be saved each year.

Let the total amount to be saved each year be "m"

annual return = 11.6% of m = 11.6 ÷ 100 = 0.116 of m

Therefore to be a millionaire in 40 years, the total amount saved for the year + the annual return on that amount when multiplied by 40 will yield 1 million. It is represented thus:

(0.116m + m) × 40 = 1,000,000

= (1.116m) × 40 = 1,000,000

44.64m = 1,000,000

∴ m = 1,000,000 ÷ 44.64 = 22401.433691756

therefore amount to be saved for a year = 22401.433691756

to calculate amount to be saved each month we divide this amount by 12, because 12 calendar months make one year. Hence;

amount to be saved each month = 22401.433691756 ÷ 12 = 1866.79 (to 2 decimal places).

b. If you wait 10 years, then you have only 30 years left to save

since the annual return remains the same,

(0.116m + m) × 30 = 1,000,000

(1.116m) × 30 = 1,000,000

33.48m = 1,000,000

∴ m = 1,000,000 ÷ 33.48 = 29868.578255675 (amount to be saved for a year)

Therefore amount to be saved per month = 29868.578255675 ÷ 12 = 2489.05 ( to 2 decimal places)

c. If you wait 20 years before saving, you hve 20 years more to save.

Since the annual return remains the same;

(1.116m) × 20 = 1,000,000

22.32m = 1,000,000

m = 1,000,000 ÷ 22.32 = 44802.867383512 (yearly amount to be saved)

Therefore amount to be saved per month = 44802.867383512 ÷ 12 = 3733.57 ( to 2 decimal places).
