Answer:

$21,623.70

Step-by-step explanation:

A suitable financial calculator can compute the beginning balance and the remaining balance for you. The attachments show a TI-Nspire calculator's TVM solver app being used to answer this question.

The first attachment shows the computation of the loan value. It is about $37,624.54.

The second attachment shows the computation of the remaining balance after 16 of the 32 semi-annual payments have been made.

The loan balance 8 years from the end of the loan will be about $21,623.70.

Pls help me!!!! I'm stuck on how to solve this!!??

Luda [366]

Let A represent the value of the car after each year.
A= initial value (P)×(1+percent increase(r)) ^time
A=P×(1+r)^t
A=18710×(1+(-12%))^8
A=18710×(1-12%)^8
A=18710×(1-0.12)^8
A=18710×(0.88)^8
A= 6728.7619591115
The best approximation is 6729
Therefore the value of the car will be about $6729 after 8 years
Your answer is B.

Which answer represents a geometric sequence?

exis [7]

Answer:

{−1008,−504,−252,−126,…}

Step-by-step explanation:

-504÷(-1 008)=0.5

(-252)÷(-504)=0.5

(-126)÷(-252)=0.5

In this sequence ,we multiply by 0.5 each time to get the next term

then it’s a geometric sequence.
