Your aunt bought a new car. After three months of car payments she owed a total of $22,275 to the bank for the car loan. After 12 months, she owed $18,900 to the bank for the car loan. What was her average payment rate on the principal of the car loan during this time?

Answers

Answer 1
Answer: Given:
Balance after 3 months = 22,275
Balance after 12 months = 18,900

$22,275 - $18,900 = $3,375

12 months - 3 months = 9 months

3,375 / 9 months = $375 per month.

375 x 12 = 4,500
4,500 + 18,900 = 23,400 principal amount.

375 / 23400 = 0.016 
0.016 x 100% = 1.60%

The principal of the car loan is $23,400
The interest rate of the car loan is 1.60%
The monthly payment is $375.
Answer 2
Answer:

Answer:

You can find the rate of change by dividing the difference in the principal owed by the difference in the number of months.

18,900 – 22,275 / 12 – 3 = -375

The average payment is $375 per month.

The values in the table represent a linear function. what is the common difference of the associated arithmetic sequence?x: 1, 2, ,3 ,4 ,5
y: 6, 22, 38, 54, 70.

A) 1
B) 20
C) 16
D) 5

Answers

Answer:  The correct opion is

(C) 16.

Step-by-step explanation:  Given that the values in the following table represent a linear function.

x:       1,     2,    3,     4,    5

y:       6,    22,  38,  54,  70.  

We are to find the common difference of the associated arithmetic sequence.

If y = f(x) is the given function, then we see that

f(1) = 6,  f(2) = 22,  f(3) = 38,  f(4) = 54 and f(5) = 70.

So, the common difference of the associated arithmetic sequence is given by

f(2)-f(1)=22-6=16,\n\nf(3)-f(2)=38-22=16,\n\nf(4)-f(3)=54-38=16,\n\nf(5)-f(4)=70-54=16,~~~\cdots.

Thus, the required common difference of the associated arithmetic sequence is 16.

Option (C) is CORRECT.

Answer:

c

Step-by-step explanation:

You can find that 22-6=38-22=54-38=70-54=16

so the answer is c 16

The mobile company charges $180 for an hour of service. How many dollars are customers charged every minute?

Answers

Answer: There are $3 charged every minute from customer.

Step-by-step explanation:

Amount charges per an hour = $180

As we know that

1 hour = 60 minutes

For 1 hour, amount would be $180

For 60 minutes, amount would be $ 180.

We will use "Unitary method":

For 1 minute, amount would be

(180)/(60)\n\n=\$3

Hence, there are $3 charged every minute from customer.

The mobile company charges $3 for an hour of service.
