The applicable formula is;
A = P(1-r)^n
Where;
A = Final purchasing power
P = Current purchasing power
r = inflation
n = Number of years when P changes to A
Confirming the first claim:
A = 1/2P (to be confirmed)
P = $3
r = 7% = 0.07
n = 10.25 years
Using the formula;
A = 3(1-0.07)^10.25 = 3(0.475) ≈ 3(0.5) = $1.5
And therefore, A = 1/2P after 10.25 years.
Now, give;
P = $9
A = 1/4P = $9/4 = $2.25
r = 6.5% = 0.065
n = ? (nearest year).
Substituting;
2.25 = 9(1-0.065)^n
2.25/9 = (1-0.065)^n
0.25 = (1-0.065)^n
ln (0.25)= n ln(1-0.065)
-1.3863 = -0.0672n
n = (-1.3863)/(-0.0672) = 20.63 years
To nearest year;
n = 21 years
Therefore, it would take approximately 21 years fro purchasing power to reduce by 4. That is, from $9 to $2.25.
Question:
Please see the Demand and Cost information reproduced in the attached table
Answer:
The correct choice is A)
Profit if maximized where price is equal to $20.
At this price, MR = MC.
Please see the attached PDF.
Explanation:
The profit-maximizing choice for the monopoly will be to produce at the quantity where marginal revenue is equal to marginal cost:
That is, the point where MR = MC.
If the monopoly produces a lower quantity, then MR > MC at those levels of output, and the firm can make higher profits by expanding output.
Cheers!
Answer:
$28,000 and $12,000, respectively
Explanation:
Marginal cost = incremental cost from Plan C to Plan D
= total cost (plan D) - total cost (plan C)
= 72,000 - 44,000 = $28,000
Marginal benefit = incremental benefit from Plan C to Plan D
= total benefit (plan D) - total benefit (plan C)
= 64,000 - 52,000 = $12,000
Therefore marginal cost and benefits for Plan D = $28,000 and $12,000, respectively
Answer:
the investment's coefficient of variation is 1.25.
Explanation:
The coefficient of variation relates the units of return to the units of risk. It expresses the unit of risk per 1% of return as follows :
<em>Coefficient of Variation = Standard Deviation ÷ Return</em>
Therefore,
Coefficient of Variation = 10 ÷ 8
= 1.25
Answer:
transferred-out 135,000
Explanation:
We solve using the following identity:
beginning WIP + cost added during the period:
total cost to be accounted for.
Then this value can be either ransferred-out r remain at the ending WIP
so we construct as follows:
beginning 0
added 180,000
Total cost 180,000
ending <u> (45,000) </u>
transferred-out 135,000
