Answer:
The correct option is 2.
Step-by-step explanation:
It is given that Jane bought a car for $30,303. The value of the car depreciated at a constant rate per year.
The exponential growth and decay function is defined as
[tex]P=P_0(1+r)^t[/tex]
Where, P₀ is initial value and r is growth rate.
The initial value of car is $30,303. Let the rate of depreciation be x%.
[tex]30303-\frac{x}{100}\times 30303=25757.55[/tex]
[tex]x=15[/tex]
It means rate of depreciation is 15%. Since the value of car decreased by 15% per year, therefore growth rate is -0.15.
[tex]P=30303(1-0.15)^t[/tex]
[tex]P=30303(0.85)^t[/tex]
Therefore option 2 is correct.
Answer:
f(t) = 30,303(0.85)^t
