Question

The value of Tonya's car is $21,000. The car's value depreciates at a rate of 15% per year.

Which function represents the value of the car after t years?

O f(t) = 1.15(21,000)

O f(t) = 21,000(1.15)

O f(t)21,000(0.85)

O f(t) = 0.85(21,000)

Answer 1

the answer for this question is: f(t)=21,000(0.85)^t

Explanation:

well since its asking what function represents the value, you have to convert the 15 percent into a decimal. so when you put the equation together you can see its 0.85.

hope it helps! :)

Answer 2

f(t) = 0.85(21,000)

Explanation:

100% - 15% = 85% 0r in decimal form 0.85

0.85 x the original pricen 21,000
