Answer:

Step-by-step explanation:
Let the exponential function be,

Here, C = cost of the car
t = Duration or period in years
From the given table,
Two points representing cost of the car and time are (10000, 0) and (8520, 1),
For (10000, 0),

a = 10000
For (8520, 1)
8520 = 

b = 0.8520
Therefore, exponential equation will be,

Answer:
$574.41
Step-by-step explanation:
multiply 30 by dollar to pesos
A. Multiplied by 2 for the first then for the second multiply by three.
Explanation: the equations already have opposite signs for y so reversing the signs would be counterproductive. (Eliminates B and D) and the easiest way is to get the numbers before the Y variable to be the same. The top by 2 and bottom by 3 would do that, leaving only A.
