Someone pls help me with this question I can’t figure it out because we haven’t being given either k or a
You're told the value of the car when it's new, i.e. when t=0.
What does equal?

ah ok its 1 so 12499 = A1 meaning A = 12499 can i apply this to my equation 7000 = AK^36 meaning 7000= 12499K^36

Yes.

Yes.
ok thanks after going through with (ii) i didnt get the right answer given what have i done wrong?
7000= 12499k^36
log7000 = log12499k^36
log7000 = 36log12499k
log7000 / 36log12499 = k

Forgot your rules of logs
Corrected.

ok i did actually try this but i got lost when i my answer ended up being
k = log 7000 - log 12499 / 36log
i dont know how to divide by 36log?

Corrected my previous post.
So,
Rearrange and taking logs:
And
Work it out and then take the antilog.
