The answer is B.
You need to subtract 15% each year from the value of the car.
50/1000 = 0.05 times is the answer
1) 0.0123456789
2) yes
3) yes
4) 1,073,741,824
5) 1.00000000E + 15
XY = xZ
85b + 83 = 91b - 283
Subtract 85b from both sides:
83 = 6b - 283
Add 283 to both sides:
6b = 366
Divide both sides by 6:
B = 61
Now replace b with 61 and solve for the length:
85(61) + 83
5185 + 83 = 5268
The length is 5,268
