b.

About how long will it take for James's car to be worth $6733?

Answer 1

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

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 :(
