Answer:
Step-by-step explanation:
The rate of decrease rate is exponential. We would apply the formula for exponential depreciation which is expressed as
A = P(1 - r)^ t
Where
A represents the value of the car after t years.
t represents the number of years.
P represents the initial value of the car
From the information given,
P = 20000
r = 20% = 20/100 = 0.2,
Therefore, the equation that represents the value of the car over time with t expressed in years is
A = 20000(1 - 0.2)^t
A = 20000(0.8)^t
