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,

The Numerator is 1, which is the top. The Denominator is the 8. I like to remember (D)own is the (D)enominator.
Answer: The snack shop sells granola bars for a lower price.
Step-by-step explanation:
First you should plug in the number of bars for each equation, if you get one bar from the snack shop the price would be $1.25, I'm going to fill in the table to help you better understand.
y= 1.25(2) 2.50
y= 1.25(3) 3.75
y= 1.25(4) 5.00
y= 1.25(5) 6.25
This table was all for the snack shop.
