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.
Answer:
c. buying rupees from National Bank at the ask rate and selling them to American Bank at the bid rate.
Explanation:
- Locational arbitrage is a strategy in which one seeks profits from the difference in exchange rates for the same currency at different banks.
- In our case for locational arbitrage one will have to buy Indian rupee from National bank at the ask rate and then sell them to American bank at the bid rate to make profit.
Answer:
The answer is C and I am sure about that, so choose C
Answer:
-Tax rates
-The general level of stock prices
Explanation:
The factors that a firm cannot control are the ones that it has no power to decide and they are determined by a third party. According to that, from the options given, the factors that the firm cannot control are tax rates because they are established by the government and the general level of stock prices because it is determined by the supply and demand in the market.
The other options are not right because the company can establish its process to evaluate investments and expenses and how to finance its assets with debt and equity.
