Answer:
Step-by-step explanation:
- Deposit amount P = $4200
- Interest rate r = 3 1/2% = 3.5% = 0.035 PA compounded semiannually
- Compound n = 2 per year
<u>Calculations as per following questions</u>
- a. I = $4200*(0.035/2) = $73.5
- b. A = $4200 + $73.5 = $4273.5
- c. I = $4273.5*(0.035/2) = $74.79
- d. A = $4273.5 + $74.79 = $4348.29
- e. I = $4348.29 - $4200 = $148.29
- f. I = $4200*0.035 = $147
Answer:
6^ 3/4 x^ 3/4
Step-by-step explanation:
I think I'm not completely sure
The answer is 1,486.6 if my calculations are correct. Anyways if you divide and your answer has a remainder just add a decimal before the remainder and add a decimal at the end of 3 and after you add a 0 in front of your decimal that is by 3 Hope this helps :)
Answer:
13
Step-by-step explanation:
Its calculate the common difference first.
(95-11)/(n-1).
We also have the sum of these n terms is 689.
So we have the following:
11
+(11+(95-11)/(n-1))
+(11+2(95-11)/(n-1))
+...
+(11+(n-1)(95-11)/(n-1))
This can be re-expressed alittle:
There are (n) amount of 11's in the addition... also 1+2+3+...+(n-1)=(n-1)(n)/2.
So we have the sum is
11(n)+n(n-1)/2×(95-11)/(n-1)
But this equal to 689.
We need to solve the following equation:
11(n)+n(n-1)/2×(95-11)/(n-1)=689
The (n-1)'s in second term can cancel.
11(n)+n/2×84=689
11n+42n=689
53n=689
53n=689
n=689/53
n=13
