Homework Help: Pre-Algebra

Posted by Dean on Tuesday, October 27, 2009 at 11:30pm.

Can I have someone check this please?
I wouldn't want to do the whole page, then find out I had done them all wrong. :(

[Percents of Change]

A $100 digital watch is now $72
Decrease, 72/100 = negative percent.
100/72.00 = .72
.72 - 1 = 30%?

Thanks.

30% is my final answer, correct?
