Question

What’s the initial value and value after 13 years

Answer 1

we have given the expression
`v(t)=20000(0.86)^t`.

we need to find the cost of car initially and after 13 years.

we know that at initially t will be 0.

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

so initially the cost of car is 20000.

when t=13
`v(13)=20000(0.86)^(13)=2815.20`.

so we have plugged corresponding time and found the cost by using the given equation.
