Sagot :

Answer:

D) a 13% decrease in value each year

Step-by-step explanation:

Perry used the formula V (t) = 24,450(1-0.13)^t to find the value of his car t years after he purchased it.

What does 0.13 represent?

The expression given above represents and expression of exponential decrease.

This is represented by the formula

y = a(1 - r)^t

Where

y = Value after time t

a = Initial value

r = Rate of decrease

t = Time

Comparing both expressions

y = a(1 - r)^t = V (t) = 24,450(1-0.13)^t

We can see that:

r = 0.13

This is the rate of decrease.

Converting to Percentage = 0.13 × 100

= 13%

Option D is the correct option.
