Step-by-step explanation:
Answer:
a. $311,555.26
b. $500,000
c. $188,444.74
Step-by-step explanation:
The computation is shown below:
a. Here we have to determine the present value
Given that
PMT = $25,000
NPER = 20
RATE = 5%
FV = $0
The formula is shown below:
= -PV(RATE;NPER;PMT;FV;TYPE)
after applying the above formula, the amount that need in the beginning is $311,555.26
b. The total money should be
= $25,000 × 20 years
= $500,000
c. The amount of interest is
= $500,000 - $311,555.26
= $188,444.74
Answer:
![[B]=2](https://tex.z-dn.net/?f=%5BB%5D%3D2)
Step-by-step explanation:
![B=\left[\begin{array}{ccc}3x-5&-3+2y\\11-3x&2y-5\end{array}\right]](https://tex.z-dn.net/?f=B%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3x-5%26-3%2B2y%5C%5C11-3x%262y-5%5Cend%7Barray%7D%5Cright%5D)
With
and 
![B=\left[\begin{array}{ccc}3(3)-5&-3+2(4)\\11-3(3)&2(4)-5\end{array}\right]](https://tex.z-dn.net/?f=B%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%283%29-5%26-3%2B2%284%29%5C%5C11-3%283%29%262%284%29-5%5Cend%7Barray%7D%5Cright%5D)
![B=\left[\begin{array}{ccc}9-5&-3+8\\11-9&8-5\end{array}\right]](https://tex.z-dn.net/?f=B%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D9-5%26-3%2B8%5C%5C11-9%268-5%5Cend%7Barray%7D%5Cright%5D)
![B=\left[\begin{array}{ccc}4&5\\2&3\end{array}\right]](https://tex.z-dn.net/?f=B%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4%265%5C%5C2%263%5Cend%7Barray%7D%5Cright%5D)
solving the determinant of matrix B
![[B]=\left[\begin{array}{ccc}4&5\\2&3\end{array}\right]=(4.3-5.2)=(12-10)=2](https://tex.z-dn.net/?f=%5BB%5D%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4%265%5C%5C2%263%5Cend%7Barray%7D%5Cright%5D%3D%284.3-5.2%29%3D%2812-10%29%3D2)
248,700
682 is closer to 700 than to 600
The answer is 7 because 70 ÷ 10 = 7.
