What 97.645 rounded to the nearest tenth

Answers

97.645.

The tenth digit is 6. The digit after that is 4, and it is not up to 5, so we round it down. If it was up to 5 or more we would have added 1 more to the 6 to become 7, but since it is not up to we leave the 6 that way. 

97.645 ≈ 97.6  rounded to the nearest tenth.
The tenth digit is 6. The number after it is 4. So the 6 stays the same. It is 97.6

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

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:

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.
