Question

The value of a car, C(t), t years after 2011, is modeled by the following function.

C(t) = 50,000(0.9)^t - 2,000

I have taken the test on Plato and have answered correctly.

Answer 2

9514 1404 393

Answer:

B

Explanation:

At t=0, the value is ...

C(0) = 50,000·(0.9^0) -2000 = 48,000

At t=20, the value is ...

C(20) = 50,000(0.9^20) -2000 = 6079 -2000 = 4079

The only graph that matches these end points is B.
