The answer is A ..................

Answer 2

Answer:

A.The decrease in the value of the truck which is 12%.

Step-by-step explanation:

We are given that a function

$f(x)=29000(0.88)^x$

Where f(x) represents the value o a truck in dollars after x years.

We have to find that 0.88 what represents in the given function.

Substitute x=0 then we get

$f(x)=29000(0.88)^0=29000$

The value of  a truck initially=$29,000

The value of any object after x years is given by

$f(x)=a(1-\frac{r}{100})^x$

Where a= Initial cost of object

r (in %)=Decrease in the value of object

x=Time ( in years)

When time spend the value of truck decreases.

By comparing the value then we get

$1-\frac{r}{100}=0.88$

$\frac{r}{100}=1-0.88=0.12$

$r=100\times 0.12=12$

Hence, the decrease in the value of the truck which is 12%.

Option A is true.
