Question

What’s the initial value and value after 13 years

Answer 1

we have given cost function which is exponential
`v(t)=20000(0.86)^t`.

we need to find the cost of a car at time t initially and after 13 years .

we need to plug t=0 and t=13 in v(t).

`v(0)=20000(0.86)^0=$20000`.

and
`v(13)=20000(0.86)^(13)=$2815.20`.

so the value of car is initially $20000 and after 13 years it was $2815.20.
