Exponential Decay

Step-by-step explanation:

we know that

The equation of a exponential decay function is given by

[tex]y=a(1-r)^x[/tex]

where

y is the value of the truck

x is the number of years

a is the initial value

r is the rate of change

we have

[tex]a=\$22,000\\r=14\%=14/100=0.14[/tex]

substitute

[tex]y=22,000(1-0.14)^x[/tex]

[tex]y=22,000(0.86)^x[/tex]

Find the value of the truck after 8 years.

For x=8 years

substitute in the exponential decay function

[tex]y=22,000(0.86)^8=\$6,582.79[/tex]
