James bought a $19000 new car. It is estimated that the value of his car will depreciate at a rate of 9% each year.
a.
Write an exponential to model this situation.
b.
How much will James's car be worth in 4 years?
C.
About how long will it take for James's car to be worth $6733?

A. I think you have to draw a graph or something, I'm a little confused on A.

B. about 7 years and 2 months

C. $12160

Step-by-step explanation:

$1900 x .09 = $1710 yearly

1710 ÷ 12 (months) = $142.5 each month

B. I kept subtracting 1710 until i got to 7030. From 7030, I subtracted by 142.5 and got 6745 but not 6733

So I'm not sure if you shoukd use my answer. I did try my hardest, but still wasn't able to get exactly 6733.

C. $1710 × 4 = 6840

19,000 - 6840 = $12160

I hope this was helpful. Apologies if I did not give you the answer you wanted :(
