The answer is: APR = 10.56%
Explanation:
Using an excel spreadsheet and the RATE function, we can calculate the monthly interest rate of buying the car:
=RATE(72,-489,25995)
= 0.8803% monthly interest rate
Then we multiply the monthly interest rate by twelve to get the APR:
APR = 0.8803% x 12 = 10.56%
For 3 sides to form a triangle two sides added together need to be greater then the 3rd side. You need to check all 3 combinations:
1. 11.5 + 10.5 = 22, 22> 6.1
11.5 + 6.1 = 17.6 17.6 > 10.5
10.5 + 6.1 = 16.6, 16.6 > 11.5
This one can make a triangle.
2. 9.5 + 3.5 > 4.5
9.5 + 4.5 > 3.5
4.5 + 3.5 < 9.5
Cannot make a triangle.
3. 8 + 6.7 > 1
6.7 + 1 < 8
Cannot make a triangle.
4. Can make a triangle
5. Can
6. Can
A.) 50.45m + 60 = 57.95m
b.) 50.45m + 60 = 57.95m
60 = 57.95m - 50.45m
60 = 7.50m
60 / 7.50 = m
8 = m.....so the cost will be the same at 8 months
(y - 0.18y) * 1.08
Just explain what each part of it means and try to make it seem long.
It would be 50 because the 5 is in the tens spot
