I = P x R x T
$249.60 = $640 x R x 6 1/2
$249.60= 4160 x R
$249.60/4160 = 4160 /4160 x R
R= .06 * 100 = 6%
Check
I = P x R x T
$249.60 =$640 x 6% x 6 1/2
$249.60 = $249.60
The answer to 7 is 9 times and the answer to 8 is 248 car owners

If it keeps going at the same amount added per week, the two will never reach the same amount.
By solving a linear equation we will see that the initial temperature was 66 degrees.
<h3>
What was the initial temperature?</h3>
Let's define T as the initial temperature.
First, it increases by 18 F, then it decreases 6 F, and finally, it increases another 12 F, such that the end temperature is 94F.
Then we can write:
T + 18F - 6F + 12F = 94F
Now we can solve that linear equation to find T.
T = 94F - 18F + 6F - 12 F = 66 F
In this way, we conclude that the initial temperature was 66 degrees.

Answer:
as the point (8,0) lies on the x-axis (east) and the bearings are defined with respect to south or north according to the rotation as well. so here the angle is 90 and the directions are N90E or S90W
