9 answers

0.8x = 18,000

Solve for x.
What is x?
x = cost when new
how do you put it in a sequence
0.8x = 18,000
x = 18,000/0.8
x = 22,500
Would this be a arithmetic sequence
No. I don't know what a sequence has to do with your original problem.

Please explain.
Can you write it in a sentence
When the car was new, it cost $22,500.
