Answer:
Calculate the true APR:
It is given that the compounding period is 12 as the payment is done monthly. The total loan amount is $1,000 with $100 monthly installments at an interest rate of 20%. Annuity is a stream of cash flows that continues for a given number of years. The interest rate is calculated by following method. Use the following formula to calculate the present value:
Where,
c —) Monthly payment
r —> Interest rate
t —> Compounding period
Now,
![1000 = 100[\frac{1}{r}-\frac{1}{r(1+r)^{12} }]](https://tex.z-dn.net/?f=1000%20%3D%20100%5B%5Cfrac%7B1%7D%7Br%7D-%5Cfrac%7B1%7D%7Br%281%2Br%29%5E%7B12%7D%20%7D%5D)
We cannot determine the exact value of interest of annuity. Using the trial and error method we can determine the interest rate. We can use the TVM (time value of money) keys in the financial calculator to calculate the value of 'r' as below:
Enter
N = 12
PV = -1000
PMT =100
FV = 0
Now press i and we should find that the monthly rate for this annuity(r) is 2.923% per month.
Effective interest rate is the annualized interest rate using compound interest. Multiply the monthly rate by 12 to obtain APR as below:
APR = Monthly rate x 12
Substitute the values in the formula:
APR = 2.923% x 12
APR = 35.076%
Hence, the APR is 35.076%.
Determine the effective annual rate (EAR):
It is the net annual return received. The monthly rate should be used to calculate the effective annual rate with the help of the formula below:



Effective annual rate = 0.41302 or 41.302 %
Hence, the effective annual rate is 41.302%.
Finally we may conclude that the true rate would be 20%, if $1,000 was borrowed today and $1,200 was paid back one year from today. It should be noted that the true rate must be greater than 20% because the twelve annual payment of $100 should be made before the end of the year.
Answer choice C. is the best one
Answer: annual rate of return
Explanation:
The simple rate of return is also called the unadjusted rate of return or the accounting rate of return.
The simple rate of return is calculated when the incremental net operating income for the year is taken and then divided by the initial investment.
It should be noted that it's not called the annual rate of return.
Answer:
C. Greater than $6 but not greater than $9
Explanation:
The computation of the unit holding cost per year is shown below:
As we know that

where,
Annual demand is 450 × 52 weeks = 23,400 units
Ordering cost is $35 per order
Economic order quantity is 468 units
Now placing these values to the above formula

Now to find out the carrying cost, the calculation is given below:
= (2 × 450 units × $35) ÷ 468^2
= $7.48 per unit
The carrying cost is also known as holding cost
He should price them by taking 90 percent and dividing by .32
