a new automobile depreciated 20% of its value after 1 year. if the automobile is priced at $18,000 after 1 year, what was its cost when it was new?

math  Ms. Sue, Tuesday, August 14, 2012 at 5:27pm
0.8x = 18,000
Solve for x.

how do you put it in a sequence

math  Ms. Sue, Tuesday, August 14, 2012 at 5:48pm
0.8x = 18,000
x = 18,000/0.8
x = 22,500

Would this be a arithmetic sequence

math  Ms. Sue, Tuesday, August 14, 2012 at 5:59pm
No. I don't know what a sequence has to do with your original problem.
Please explain.
