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:
The correct answer is: medium of exchange.
Explanation:
The medium of exchange function of money that helps the society in gaining the benefits of geographic and labor specialization.
The medium of exchange function means that money is an asset that is widely accepted as a medium of exchange in the transactions involving the exchange of goods and services.
The medium of exchange function of money eliminates the need for double coincidence of wants. Thus helps in labor and geographic specialization.
C. a negative duration on it's assets.
Consider the demand equation q=20,000 p^(-1.4). if the cost of production is constant at $0.50 per unit $1.75 is the optimal price to maximize profit.
The income maximization system depends on income general sales overall fee. consequently, a firm maximizes earnings while MR = MC, that is the primary order, and the second order depends on the first order. This idea differs from wealth maximization in phrases of length for income earnings and the company's goals.
Calculation,
The demand equation q=20,000 p^(-1.4)
The production constant is $0.50
maximum profit= $1.75
The choicest charge is that charge point at which the total earnings of the seller are maximized. while the rate is just too low the vendor is shifting a big quantity of devices but income is the best possible combination of income. Examples of income maximizations like this encompass: discovering less expensive raw materials than those presently used. discover a provider that gives better charges for inventory purchases. locate product resources with decreased delivery prices. lessen labor expenses.

Answer:
Card Verification Number
Explanation:
The card verification number is the additional code printed on the back of the debit or credit card. On most cards it is the last three digits printed on the signature strip located on the back of the card. On American Express (AMEX) cards, this is usually a four-digit code on the front of the card. Since this number is not embossed (like the card number), it is not printed on receipts, so it is unlikely that anyone, In addition to the actual cardholder, know him.
