Answer:
The correct answer is A. $18,276
Explanation:
First you have to calculate how much you'd end up having at the end of the 25 years period in your savings account.
You calculate the total amount saved for each year, using the formula:

Where
is the total amount in the savings account for this period.
is the total amount in the savings account from the previous period.
is the interest rate.
are the annual deposits being made into the savings account.
Therefore for the first year you'd do:


For the second year:


And so on. You can help yourself calculate the value of this series using programs like Excel.
I have attached an Excel file that has a table with the savings values for each of the 25 years.
So, the 25th year you’ll have $365,529.70 in your savings account. Now you simply divide this number by 20 (that will be the number of years you’ll be withdrawing the same dollar amount from your savings account):

In conclusion, you’d be able to withdraw $18,276.485 each year for the following 20 years after the 25th deposit, if all withdrawals are the same dollar amount.
Answer:
False
Explanation:
Most interest rates in the economy are not set by federal reserve. For example, banks decide what interests to pay different kind of deposits and charge loans of different risks on their own (with consideration for competition and profitability).
What the Fed does is set important rates (discount rate and funds rate) that influence other interest rates in the economy.
Answer: 90.32%
Explanation:
Weekly demand (d) = 120
Standard deviation = 10
Lead time (l) = 4
Reorder point = 506
The reorder point is calculated as:
506 = 120 × 4 + Z × 10 × ✓4
Solving for Z will give us 1.3
Then, we check this in the z table which will give us p = 0.9032
Therefore, the service level is 90.32%.
Answer:
$61,445.20
Explanation:
we need to determine the present value of an annuity, and the simplest to determine this is by using annuity factors:
number of payments = 20
interest rate = 7%
annuity payment = $5,800
present value of the annuity = $5,800 x 10.594 (PV factor, 7%, n= 20) = $61,445.20
if we do not have an annuity table at hand (or in the internet), the formula used to calculate the annuity factor is:
annuity factor = [1 - 1/(1 + r)ⁿ] / r
Answer:
b) it is impracticable to determine some period-specific effects.
c) it is impracticable to determine the cumulative effect of prior years.
Explanation:
According to the actual normativity these are the two options more consistent with the exercise.
